Acer are clones from Pinemeadow Golf in the States. And yes X18s.

Should you worry? Some people don't like clones but a mate of mine has a pinemeadow* rip off of an old Taylor Made driver, with a steel shaft and when he whupped my ass last time out he was hitting it a country mile.

The thing with clones imo is not so much the head but to make sure you get a decent shaft that suits you.


* Actually bought in UK from component club fitter
