The regular clash takes weight just like any other frame. I've added 4g between 3 and 9 and 1g at 12, then 10g in the handle with a leather grip.Since you have both ... is there difference in spin between regular and pro? I'm playing vcore pro both 97 and 100 at 11.6 oz. Not sure the clash pro has room to modify and some have said regular clash doesn't like added weight.
Thanks.
You'd find it hard to feel a difference between the two frames now they weigh the same.
