My 1st has never been better, but I am also working on it with a great pro this year.
Also, one of our league players has a pro-speed 1st serve and when he switched to the 400T his serves quickly became unreturnable.
I hope you work it out. BTW we both play with leather grips.
I should have noted that a chronic shoulder injury that I've been working at overcoming has depleted some of my shoulder action, so I've been relying more on racquet head mass than great shoulder action to generate pace on my first serve.
Have already applied the leather grip and looking forward to round two.
