Good hitting guys (although there will undoubtedly be people rating you 3.5's
My game is similar to yours in that 2-handed bh is better than bh slice... so I write a mental note to myself that if I can get into a position to hit a backhand, I'll hit a 2hbh every time instead of a slice. Slice is a good weapon to have but why hit it if it's failing on you.
Also I think your forehand take-back is too short. Have you tried taking a bigger backswing?
