I have both a 750DP and a 750VS.
The reason I retired the VS, is because I can't wait for the Secondaries to open. When I burp the throttle, in town, it is rarely for more than at most 2 seconds because 3 seconds from 30 mph is gonna put me up some poor unsuspecting soccer-mom's tailpipe.
So therefore, I bolted on the DP. Now, when I nail it, chit happens..... not always goodchit, but daymn it can be exciting.
