I'm happy with my driver - it's a Cleveland hibore XL 10.5 degree with the Gold stiff flex stock shaft. Earlier this year, I hit a drive and something appeared to break loose inside the head. Sounds like a couple loose objects inside.
I thought I had ruined it, so took the opportunity to "upgrade" and try something I had my eye on - the newer HiBore XLS in 9.5 degree with the Red version of the stiff flex shaft. After a few months of trying to adjust to the new club, it just wasn't working. Ball flight definitely lower and longer, more roll, but felt terrible and hitting all over the place, just not feeling right.
So last week I sold the XLS on craigslist and put the XL back in the bag, it still feels great and I'm hitting fairways again.
The problem is it has this rattle sound inside the head. Sometimes the sound will go away for a few holes or a whole round, where I guess the debris gets stuck somewhere in one of the corners of the HiBore's unusual head shape cavity.
Most people say it's epoxy from the shaft joint which has come loose. I had one person suggest there is an internal weight which has come loose. And one person said something about foam coming loose in the head. Never heard about foam in a driver head.
The club is from 2007 I think, I am second owner. Therefore I would think there is no warranty I could pursue. I wish the regional Cleveland rep would be around at a local demo day soon so I could ask him about it.
Anyone had something like this happen, any suggestions?
