Hi Wayne, have had several Trackers over the years (wouldn't mind another one actually, as they are a bit of fun ), and 10.5ft.lb is the best I ever experienced, usually 10ft.lb, so at 9.5ft.lb, I'd leave well alone, as it is not worth the re-springing hassle involved for an extra half of 1ft.lb of power. Therefore, imho, enjoy it for pleasure plinking as is (just my take on it ). Atb: G.
