In the interest of geeking things up and kicking off another epic doona love/hate thread, here's a huge cut and paste job from the foilzone arcusers files...
A list of all the mods you can do to your venom....
SFS MOD ("SHORTEN FRONT STRAP"), ON VENOM 1 - FUNALEX SAYS:
You can easily imagine a profile with 4 internal adjustable strap (a =
leading edge, e = tet (trailing edge))
Shortening a: (front strap)
The profile bends on the nose, the profile less prone to stall, point
upwind very well, more power. Little less stable (but on venom the SFS
isn't too hard, and the kite keeps very stable, no problem).
Shortening b: (second front strap)
This point is aligned with the COP (center of power), so the effect isn't very
important... and it could shorten the entire kite and lower the AoA of
the kite, it become unstable, be carefull !
shortening c: (middle strap, DOES NOT EXIST ON VENOMS, just for the sake of
understanding how these profile changes work aerodinamically)
Imagine an middle internal strap, shortening it transforms the profile
in a very reflex profile...very very stable, more stall, good gust
absoption. But not really a way to increase power at the edge of the
wind window.
shortening d: (rear strap)
The profile of the kite become more reflex on the rear part, and the
stability is better, but it's more prone to stall, and the power isn't
realy increased ... less upwind performances.
shortening e: (its not really a strap, it is the effect of TET)
The profile become more powerfull, but the kite can't really reach the
edge of the wind window.
You can do a mix :
shortening a+c:
powerfull kite, pointing upwind, really stable.
shortening a+e:
less stable, good upwind, good power.
shortening a+d+e:
Really powerfull, upwind correct. stability correct.

SMS MOD ("SHORTEN MIDDLE STRAP") on VENOM 1 - GAMELORD & LACH SAYS:
We have been shortening the 2nd braid (b braid in FUNALEX words, middle one on Venom)
in the center of the kite (reach through the deflate zip) and it speeds the kite up
tremendously. Shortening the same amount on the wings (inside of the inflate zippers)
will make the kite turn quicker. Shorten both the center and the tips for the max
performance gain. Everyone here has dropped the Bob's bridle line, it does help but with
the other mods it really isnt that necessary. The TET is a great mod on the
V1's but is the most time consuming to install but still is very easy to do, takes very little
time (about a half hour) and can be installed without having to knife into the kite at all.
The other mods (SFS - wing tips) takes about 5 minutes to install and again, no knifing
into the kite at all to do them. I highly recommend the SFS and wing tip on all the Venom
1's to all our customers. The TET is optional as the
kite flies awesome without it...but if you get bored and want to tweak it a little, put it in.
The actual amount of TET installed will depend on your personal
preference.
BSR MOD ("BOBS SHOULDER RECONSTRUCTION") on VENOM II - BOB DAWSON SAYS:
In the standard production form, I used the kite with the outer adjustment on the
third braid at 50 per cent and the centre usually 50 per cent. This seemed to give me the
the best performance. It gave me good power good turning and good up wind ability. The
only thing that I found a little disappointing was the ability to pop some big jumps. I'm
talking height not length or hang time.
Now after doing the shoulder reconstruction I find I have more power through the turns,
much more straight-line speed, more depower, all in all a much more nimble and
responsive best. I just love this thing. The height of the jumps I thick are at least 30 to
40% higher.
The reason is because now the kite doesn't pull me of the rail and it is much easier to load
up the board before sending the kite back. Also the up wind ability has improved
dramatically. Also I have now removed the Bob's bridal simply because the kite has heaps
of speed through the terns it does not need the bridal to stop it from
flaring. I think without any doubt the shoulder reconstruction is probably the biggest
single improvement that I have been able to come up with and there has been a few good
ones in the past. I now use the kite with the outer adjustments on the third braid at 50 per
cent and the centre adjustment completely let off. The kite generates far
more power with this setup simply because it flies much quicker. But of course that could
be personal taste.
I have not yet tried tampering with the trailing edge in terms of the ribbon idea, simply
because to really understand each modification I need to work on one before I move onto
the next. Lach if you are tuned in it would be good if you could experiment a little bit
more with just one of the mods and give us some feedback. The good thing
about both of these modification is that they are so so easy to do. As yet I have not had a
chance to do it to the venom (I) but I plan to just free up the second braid because it is not
floating and give the shoulder reconstruction a go.
Shoulder reconstruction for the venom II . Simply drag the number
one and number two strap out through the inflation zips at each end
of the kite. Boom Boom job done, how easy is that.
