I’m not arguing with anyone, as I said......”imo” the OP’s proposed build isn’t in need of a DP carb.

Everyone has their own set of priorities, and will build/buy as they see fit.
I’m sure if/when he decides a DP carb will be a worthwhile upgrade, he’ll get one.

If I were in his shoes, with a basically new 750vs in my possession, I wouldn’t be looking for another carb for the planned combo.
