I really like the Wasp. I currently have two flat Z's, one well broken in, and the other brand new. Both handle wind well. The broken in one has the flight of something like a TeeBird, very straight, maybe a touch of high speed turn, and realiable fade at the end. The new one is still very HSS, and stronger fade at the end. I've tried several Rocs and wanted to like them, but just couldn't do it, the Wasp seems more OS than any Rocs I tried. The Wasp has good glide, and seems to stick pretty well to where it lands for me.
An MVP Vector flies more Roc like to me or as I would put it, it flies like a very well broken in/seasoned Wasp, that's why the Vector has kind of found it's way back to my bag.
A well broken in Wasp and ESP Zone should fit in a person's lineup nicely. I have an ESP Zone and a Z Hornet, but haven't really felt the need for either of them lately.
