So now that I am a XXIO guy, I've learned a bit more.
The PRIME line of clubs are not counterbalanced at the butt end. The 43g grip does not have a butt weight, nor does the shaft.
There are shitloads of used XXIO clubs at 3balls.com that are priced VERY reasonably, especially when compared to MSRP. The ones I bought were in excellent condition.
Buying new clubs from XXIOUSA.com is easy and they ship a few days after ordering. They must not have a supply chain issue.
If you are older and/or less flexible AND can get used to ultra-light, high-torque shafts, these clubs will give you back some lost distance. The Prime irons are offset high launching shovels, but that's my bag.
