and why do you desire to flatten out your serve?
With this new grip (Serve Doc calls it the "Pro Grip" -- it is in between the Continental and Eastern BH grip) I am occasionally hitting 90 mph serves.
But it is by accident. Most of the time, the serves are 60-70 mph.
Note that with this new grip, all serves, even the fast serves, do have a significant degree of slice. It is great.
Want to be able to mix up the pace. With intent. Be able to "flatten" it out.
Suspect the issue relates to proper pronation and Internal Shoulder Rotation (ISR). I also observe that I will sometimes shift the grip
midway thru the service motion and end up back towards the Continental grip. Not good. I want to finish the serve motion with the exact same
Pro Grip. There should be no reason for the grip to change during the motion if you trust the ISR/pronation.
This Serve Doc student also had a "grip slip" issue. Grip slipping from Pro Grip back into Continental.
Was not getting the right leverage angle at contact.
Pat is talking about a true conti grip. Place your index knuckle on bevel 2, (see top X below which is the first bevel to the right of the flat part), and your heel pad (see the bottom X below, which is the top flat part) on bevel 1 (2-1 grip).
A lot of people use a weak conti grip (2-2 grip) without even realizing it.
