I am 87kg. And ride a 134/44 TT. Low end sucks. i have a 12 and 10 Parks. My range is from 10 to 35 kn. I really notice the low end issues. I am considering switching to 2012, but want to test first. Other than that, i love my parks:-)
Consider the 14 if you do. It is a super fun kite, and it will probably give you that extra kick you need on the low end
That is what iI was thinking, but I believe the 12and 14 will have overlapping range, so I,d better get a LW kite like the EPIC one discussed a lot in the forum.
