Call Rob @ 619-543-9990. He'll fix ya up.
I've been using their latest called the 'Quicksilver', made by L.A. Golf shafts(formerly Matrix). Under 60 gr., 4.0 torque. I've got an R flex and it is a great shaft--(wish I had an A flex). They are not cheap at $299, but see what he has to say about them. These were around $400 when Matrix was selling them.
