Grips that absorb stiffness, or block it, or otherwise stop those horrible stiff tremors or whatever traveling into the arm/hand, etc... which are the best kind of grips, or combination of grips/overgrips/whatever in ppl's experiences for stifling the stiffness? I ask because I'm trying out a new frame but am finding it a sometimes a stiff hit (to be specific it's caused pain twinges in the vicinity of my upper outer arm area.) However, I don't want to give it up before I've properly played with it a while (strangely the frame isn't even considered stiff in terms of RA??? )... and btw, the frame has a leather grip (nothing else though on the handle) which I quite like tbh - but aren't leather grips meant to be not very effective stiffness absorbers? Anyhow, would appreciate any feedback that can recommend good grips or whatever with comfort/preventing stiff tremors getting to the arm being the goal. Thanks, R.
