Absolute best advice is to put the grip on a 7 or 8 iron.
See if you like it... My guess is you will.
The new polymers just feel 'better'...
Your hands feel like they are attached to the club.
Reminds me of a good set of snow tires vs all season tires.
Great feeling & tackiness but the true Iomics are overpriced.
Itomics are kind of a wannabee to the real things...
BTW Not sure I would want to do the re-gripping myself let a Pro do it.
