24/27/32 depending on water and wind conditions. 24 is my go to for timing sake. Sure length can slow the kite down, but the timing and vertical height for me can be comprimised, plus you tend to get more of a pendulum effect (for me) escpecially at 32. To be honest the bar is for my 10m dyno mainly on 24m lines. Except when on the ocean and hitting big kickers, then I want it as fast possible for as much height as possible. All depends on what I'm trying to improve, learn on the day, taking into account water conditions, wind strength and type and also what board I'm on at the time.
