I recently went from 1/4 reverse in thumb to 0 and I'm thinking about trying 1/4 forward in the thumb. I'm not sure what my finger pitches are exactly but just by looking I'd say they are 1/8 or 1/4 forward, I was wondering if changing my thumb from 1/4 reverse to 1/4 forward is going to cause me to need to make adjustments to finger pitches or span.

I would say my span is kind of relaxed, my stats are in my profile.
