I would probably see to change the forehand rubber instead of the blade: you mentioned that it was great for backhand, and the only complaint on the forehand is speed, but not feeling or control.
That is true and is a good point. I'll have to think about this because on the BH I can generate enough power with the Tibhar Def+, just not on the FH.
Why not try MarkV in thicker sponge on the forehand for more speed or just go for a faster rubber like Sriver also in thicker sponge. I could have suggested something much faster but you might not want a huge jump in speed. Sriver will give you slightly more speed and a bit less spin.
I also chop alot with my FH and I thought that if you do that you should stick to rubbers 1.5mm or less. Is this right? Also I like the feel of 1.5mm and I think I need that since I'm more of a beginner. Maybe a thicker sponge is worth a try though. I think I might need something a little faster than Sriver though, because the speed is not even close to what I'm looking for with the Mark V. If you can recommend something that's cheap I'd be willing to try it. Maybe something from Cole's site.
I'll have to check out the rubbers RB suggested also.
