I play a set of DCI irons from 1996.
They are awesome, but I might invest in new grips.
As you can tell, I am not an equipment *****.
So, can I just get the basic $5 grip?
Are the $10 grips that much better, or just marketing/hype/markup?
Most things in life, I buy the 2nd cheapest, unless it can be proven the product is superior.
My point is, with 15 year old grips, ANY new grip will be a big difference, even the cheapest.
