Federer Pro Staff RF97 Autograph Too Heavy?

[USPTARF97]

How was the adjustment to the drastically different balance of the Blade Pro to the RF97?
Did you ever play with the Blade v7 16x19 gut/poly or full poly? If so, how would you compare the 'free flex' softness of the Blade v7 to the Blade Pro?

My RF97’s have synthetic grips making them a bit more head heavy and the Blade Pros I put leather grips on them immediately to put a bit more weight in the tail end. Not much adjustment except for serving. The timing felt a bit different.
