45cm bar, no adjuster which could get in the way of twisting lines, while looping or tacking. Not needed anyways on this setup.
The 5 can be used very early and I pushed using the smallest possible kite for a while, but now I am more back to riding powered, so currently I am starting to use the 5 at 20knots sometimes, but mostly 25+ up to 40+ gusts.
I think if pushing it for the sake of it and with the right conditions overall something like 10, or lets say 12 knots, is possible.
Probably would use something like super thin 18-20 lines in this case. But all I am using is 7m lines on it since a few months.
Not sure if your question was really pointing this way though. Probably not really.
BTW I also like the 7m lines on the 7m HL and sometimes also on the 9m HL.
Otherwise using 10m and sometimes 14m lines on the 9 and 12.
This isn't related to riding waves specifically though.
