Any results?
I would think either DP you mention could give you off-the-line WOT bog with the converter you've got. The 750VS should work okay when tuned.

Both can be tuned to work. The 750 VS carb will be smoother
in the long run. They are very forgiving because of the automatic nature of the vaccuum secondaries.
I'd start with the 750vs they are easier to dial in.
Then experiment with the 650 Dp. With different shooters and
pump cams. You'll be a carb guru when you're done.
