I have used the Medusa Pro 869 for the last 2 years as a one foil quiver.
However, recently I have been using the Balz 808. The 808 has slightly less low end lift but has a higher top end speed and is less nervous when you are maxing it.
The Sabfoil website has a compare feature where you can compare different foils - unfortunately the 940 is not longer listed but you can compare the current range.
What size sails are you using with the 808 and what wind strength?
It's always hard to answer because everyone's idea windspeed seems to be different, but so far I have used:
4.7m 19 - 22knots
4.2m, 21 - 25kts
3.7m, 23 - 30kts
That's based on wind readings on seabreeze.
