I'm 105kg an recently picked up a new EPIC Screamer 14 ----- wind started perfectly for me yesterday blowing about 18 - 20 mph rid in a jimmy lewis supermodel 142. Great ride--- kite kicks a$$. Responsive --- loops better the any big kite i have owned or rode.
Came in - chilled and went out for a twilight sesh ---- wind had come down considerably now blown avg around 13ish lulling to 10 - 11 gustin to 15ish.
Pumped up an got on the water with an underground 144 FLX. Now i was looking for the low end of being able to ride this EPIC 14m screamer and i found it. look like to me 13 is the minimum i'll be able to ride in unless i get out a spleen monster door or a directional.
Now I have found the useable range for me 13-28. Give them a try ---- you will be pleasantly surprised.
