I think its not just the recurve that makes the yard hook so unpopular, its more like... everyone loves the s6, and everyone wants the s7! everything about it, its perfect in every way, and people want a longer version, its not about having a seven inch blade, its about having an s7.
well thats what I got from it.
thats also my opinion, I've heard such good things about the s6, that i really want the s7.

idk if that makes sense to you guys, but thats just what I got from it.
