A 16m Venom = approx 14m C = approx 12m bow.
For your weight I think it's a good choice.
ARC's aren't great for light wind. Probably good at around 15 knots up?
If you get the chance to try other types of kites, do it. There's C's, Bow's, 5th line hybrids, Flysurfers

and ARC's. One kite quivers are OK, but I like to have a choice.....maybe that explains why I've got 7 bikes.....
