I made the move from Dr98+ to Vc98+. To me the VC+ is the Dr+ turned to 11. Power is a tad better. The spin is quite comparable, I actually thought there was gonna a more noticeable difference. I feel the VC+ feels softer on the arm despite the higher ra rating. It is what surprised me the most between the two.
However the main reason I switched was the power on the serve. The VCORE is noticeably better. I already had a pretty good serve at 110+mph on the radar with my DR+, but the VC+ is even better for me. Unfortunately I have no radar readings yet but I didn’t need the radar to tell me that my speed is faster.
finally, he balance is better for me too and it made the switch even easier. I always add leather grips to my frames and the DR98+ is already quite head light. So I needed quite a bit of lead to the head to balance it. The VC+ being a bit less head light meant that for me I could achieve my power and balance targets with very little lead. Meaning that I get where I want to be with a bit less static and swing weight. For my game it was a no brainer.
Your mileage may vary, both are very good frames. Both have power and spin. Both feel quite good. It just seems that everything the DR does, the VC does it just a bit better.
