Leather grip makes racquet feel "stiffer"?

I played with my Vcore 95 for the most of the latter half of last year and it had a leather grip on (I did quite well with this setup). I think early this year in a bid to reduce the weight of the racquet, I replaced it with a synthetic grip and then it never felt the same. A few days ago, I put on a leather grip again and it doesn't feel as "mushy" and also feels "stiffer" which I like. Is this an effect of leather grips?

Yep it does. Even different types of overgrips make a difference in stiffness feel. Used to use VS original, which is very thin. Started to get arm issues. Then used Wilson pro and nothing of the sort. Shame because I love the feel of vs original.
