Ross...it's a little heavy, but you also described the BLX 95 pretty well.
I doubt you will like the Dunlops if you want power at all.
From the description you just gave, you should definitley revisit the Tfight since you basically described it to a T. I have a 325 and a 320 and I will post my impressions of both in the Tfight thread once I hit with them.
This morning I finished off Oheads and volleys extremely well. It was the first time I had felt that confident coming to net and taking the ball in the air for winners. The grip really has helped me out.
