For clarification, my Heym has the wide shallow V blade so that's what I've shot the most, but if you go thru all the pics in the DR Archive (like I did yesterday) an awful lot of the rifles (many big bores) have the smaller sharper-angled V. So I know alot of y'all are shooting this type sight. I've shot friends' rifles with it myself and haven't noticed a big diff between the two, but I really wasn't focused on evaluating the differences b/w the two types.

As I stated in the OP, my biggest challenge is finding the center (and other very experienced DR shooters have expressed the same problem when shooting my rifle); I'm wondering if the smaller V might work better for me.
