Hey Taza,
As someone earlier said quite a few out there have swapped or are swapping their explorers for evolves. Some are just keeping their explorers. As a dealer i haven't sold a single explorer since the evolve came out, and i've sold lots of evo's
... so the evolve at the moment is very much preferred.
It is a nice wing and is apparently easier to dump using the rear valve as there is better air flow round the cell (from what i've heard).
If you search the boards you'll find the following own one:
Gledders
Daz
Martin B
KeyLimePie
QBU
John B
Winnie
Wilbo
Seydiltz
PfcAJ
Rick/Frogman & a few others
I have only heard one real negative, and that is when moving your set around, you have to be careful not to drag the bottom of your wing. Also the hose routing is slightly different. Everyone i know using one seems to like it very much.
I'd get an evolve myself if i didn't have some very hard courses coming up, but i'll be getting an evo once they're out the way and i've got some time to get used to a new wing
Hope that helps,
bri
