How would the use mamiya pro force v2 graphite shaft us0103 3.7 degree torq med traj or hL us0104 4.2 degree torq high traj work for ping replacement shaft.
Both the UST shafts you list are great performers and have been for a long time. If you pick the one that fits your game the best, I can see no reason why they wouldn’t perform well. If you are looking for something similar to a shaft that was in the Ping driver, I do not know which shaft you have or the specs, so I could not tell you how similar, or not, the UST shafts would be to the one you have been using.
The ping shaft is ALTA CB 55r
