We took some of the Envys down to Cometa Copal - Costa Rica and after we got done riding some of the guys on the beach said to use "What kinda kite are you using?" We said "2013 Envy's" They said "Holy Sh*t! you we're jumping that high on an envy" lol they later ordered from us.
The 2013 Envys are pretty awesome, we use them in our school, I ride the 10.5 as my all around personal kite and the thing is a power house Super Fast and The Boost are great, but that being said when it comes to boost I prefer the HIFI X. I'm very pleased with the Envy.
We actually have some Opened unused "Pumped up for a Demo but never flown" Kites are 15,12,8 in the shop that I can sale you @ a fairly decent price.
Also a little birdy told me that the 2014's have a redesigned bridle and is even better.
if you wanna check them out.
