I've looked at this question from 3 different perspectives and I not sure how to reply b/c I am not entirely sure what you are asking us?
If you are talking about logging in practice time: I would say do whichever balance between the two percentage-wise you feel weakest on.
On rotation games, I think that the shot matters more than the shape when on offense. Honestly, there are a LOT of dependent variables you need to take into consideration when in matchplay. There is no solid answer there.
Two-way shots help out a lot, but they are harder to execute perfectly come match-time. (IMO). Its kinda like which came first the chicken?, or the egg?
Again, if you are talking about offense, its the chicken(shot) B-4 the egg (shape)
You won't get shape until you sink your shot...... :wink:
