Hello, I have been playing an epic 8.5* with the Aldila Phenom RIP 63 gram stiff shaft.  It worked well, but one of the carbon panels has worked loose.  I am looking at your ISO-T driver.  The lowest loft is 9.5*.   My swing speed is usually low 100’s occasional I will get to 107mph.  Should I go up to an x-stiff shaft to compensate for the 1 degree difference?  I was looking at your packs, I was thinking about the UST black V2 shaft.  I know it is difficult without seeing the swing or numbers, but what is your recommendation?

Also, do you have quite a few of these drivers in your shop with different shafts to try?  I live quite a ways away, but it might be worth the trip.
