Boots do not help in this impact," FORZA LEWIS".

Only one question.........why ? a 2014 pulley bridled RPM works so good.

In my experience of 2015 RPM, when a kite is charged in a jump it sit back more of 2014 at the zenit. That create more lift.
The same in a load &pop : in a loading it sit back in the window, it resist better and it's ready to shoot forward in a pop.

After 5 years ofI enjoying RPM I had 2015 13 and 11 Fuel for a couple of hours, with and without bridles. In my opinon they are enough different, also both bridled, they are not comparable: Rpm works on back lines more of a bridled Fuel.

Player 135.
I love:
top speed
amazing up wind
fantastic pop
overall balance

same performance of a 2008 132 nobile 666, but more agressive tail
