Re: [udder] Seven Pack Volume
Call up Maty and verify the Pack volume. But, I had a Seven w/ ZP foreskin on demo and, it packed down a fair amount smaller than my 280 Mojo. So I bet it would fit fine where a vented 266 used to be.
The seven is a sick Canopy, great glide, range and, powerful flare even in the deeps. . .and it packs really well. The fabric seems to lay right where you put it even when it's all slippery and new.
