Something called CT .83 or something like that.
All drivers have a mandate to be under that limit when tested by whatever golf governing body does that.
Hence you donโt get any discernible difference.
Optimizing loft and face angle for your swing is probably your best bet.
Donโt know how much the materials matter. But I imagine they further optimize things, but not to a significant degree.
Best bet is to find something that gets you 200 consistently.
Only recall this because of the Wishon 959 OL head. OL = Over Limit.
