I have been told that this particular head is light which therefore makes it harder for the club to kick through...I have asked about the 30 day guarantee on the basis that the shaft I got was the "recommended one" - I originally was going for a different model which they kindly swapped even though it hasn't worked out.
If all else fails it looks like it may be eBay bound
Check out some of the sponsors here. They can weight the head so that it performs and feels like you want it to. Adding rat glue/hotmelt to a Cally fw wood shouldn't be an issue at all to bring the head weight up.
