I want an RIP Alpha 85 Hybrid shaft - but don't want to be shafted!

Hi,

I'm wanting to purchase an Aldila RIP Alpha 85 Hybrid shaft for my 17* 910H. There are several places to buy the shaft only, but I want to make sure I get one the right tip size (.335 or .370) and can install the appropriate surefit adapter. Thanks!

.370 for hybrids
