Just to let you know I pulled the wheel forward a bit and lo and behold it shifted much better; thanks for the suggestion. As far as the A-B position, I figured the B position- 30 deg slant look more contemporary so I thought I would try it first, even though I am using a 24t max cassette. Anyway I just ordered the A position insert.
