I don't have any experience with that exact sight, but I used the VBG Angular Profix for a few months. Here are my observations.

Pros: One of the brightest sights I have ever used. The thing will actually glow in the dark. Sight is very easy to adjust, is lightweight andobviously well made. The angular pin does appear to block out less of the target.

Cons: The bubble level is too small to be effectiveand the way it is placed on the pin guard, I foundit interfered with the way I centered the orange ring in my peep. I wound up removing the level all together. My biggest complaint, and it is just my opinion, is the angular pin. For some reason, Icould never get completelycomfortable with the angular pin. I guess what I'm saying is it just did not feel natural to me.

I wound up removing the VBG and going with a conventional horizontal pin sight.
