The Alpha Luxe (60) 360 Supra-nano 560 shaft could be any flex they could free in that series: 2L, L, A, R, or S. Unless it has a marking on the shaft, as their other shafts do, only a frequency test can identify its flex. Perhaps Britt or Jim have another clue we’re missing.
To find the best shaft for you for your hybrid, I’d suggest using the shaft specs on the longest club you hit best and find a similar one for your hybrid. Remember, you can’t be sure that what the shaft label says is accurate. I’ve tested X shafts that were actually R, and vice versa. Of course, better than that is to have your local pro/clubfitter help fit you.
This may be more info than you wanted, but I hope it’s helpful! Michael
