I would try as many shafts as you can. While the latest clubs always come up with ways to improve forgiveness or accuracy, I have learned that the shaft is the engine that drives the club. One of the most interesting experiences for a golfer is to go to a fitting where they offer multiple shafts and a few clubheads and see the difference for yourself. If you just want a similar shaft the Tensei AV is available as stock.

Not much to go on here, but since you are currently gaming a Tensei (I assume Tensei Blue), I would start there. You may want to try to Kuro Kage as well since you are currently fit into a a regular flex. It's a little lighter and could give you another decent option to dial in your ball flight.

I like the Fujikura Speeder shafts.........they seem to work best for this old guy......looked far and wide to find the Fujikura Motore Speeder HB 8.8 Tour Spec S for my 17* and 21* hybrids.....also have the Speeder tour shafts on my driver and fairway..... was fitted for these clubs to get the right shafts.....

In my opinion, I would go see if there is a club fitting place anywhere near and I would just go to try out shafts. Unfortunately, I don't have money like that I would go with a Fujikura shaft. They are the best ones in my opinion for my type of swing.
