I think the calfskin grips come in a bit drier feeling, I know my Prince calfskin is dry, so maybe the other Head one is the calfskin.
Ive noticed too that older rackets with leather seem tackier, but my guess is thats 30 years of sweaty hands lol.
I find that wiping a bit of olive oil over the grip, just a smear really, gives is a slightly less dry feeling and bit of tack.
