Hey cammck
i know that ur ? isnt directed at me but...
I have a 12 mtr Helix, and have come from flying a 12mtr SS Turbo Diesel. Originally a SS 13mtr Fuel.
I,m 90ish kg on a good day

very average kiter

The Helix flys much more like a C kite than a bow, but you do have some of the depower that a bow has, not so on and off as a bow kite.
also not quite as much low down grunt as my SS Turbo Diesel 12, the kite needs to be worked more to achieve the same power (but remember these kites are on 20mtr lines, they love to be flown fast).
From what i know the Cult is a little lower aspect than the Helix, so i would expect it to have better low end.
I need aleast 16 - 18 knts to be having any fun on my 12 Helix...
hope that gives ya somthin..
cheers
