OK 5th lines are pretty old news with the rise and rise of hybrids and co. For newbies with older gear this may be very important.
I'm not wanting to start a C vs SLE discussion here but after running my two 2005 Yargas (9m & 13m) as 4 lines (largely due to slackness on my part)
I would strongly urge all newbies convert/set their C kite gear up as 5th line systems!Having recently contended with some pretty high/gusty winds and awkward locations to launch and land, I cannot rave loudly or longly enough about how cool 5th line is in every aspect.
The safety aspects alone are a huge leap forward from 4 line systems. When throwing away the bar (as newbies often do) a death spiral does not ensue, usually meaning less tangles - therefore less reluctance to do so.

Being able to trim the 5th line a little when on the upper end of your kites range (to depower) is also in the super cool category. Yep, I know newbies should never even launch if that is the case but lets face it most only buy 1 (probably 2nd hand)kite and are mega keen to get out. Also judging the wind strength is pretty tricky for some time.
My kites are 5th line designs however my bar n lines are not. Thinking this was too awkward and time consuming left the conversion in the "do it next session" basket for too long. Since the conversion I can't believe the benefits and really it only means a slightly trickier roll out of lines for mucho benefito..
Pay a shop to it today or get someone with experience to help you. Last resort check out the website of the kite and B n L manufacturer for a conversion pdf.
In the words of the great Starskie: "Do it, do it, do it"
I had my 15.5 kite (which I am yet to run as 5th yet)sewed as 5th for less than $40, and a bit more for a 5th line and yoke which is cheap cheap for such a huge safety improvement.

Neil at Hold the Line does this BTW.
I'd be interested in any feedback on postitives/problems with converting non 5th line Cs from others.
Safe kiting all...
