You can still have fun!
My old Pro 38 Dual Cam, after 8 years, started making a small "tick" when drawing. Close inspection found a small H crack in the upper limb. Finally reworked the bases of a set of Buckmaster G2 limbs, and it is up and shooting again. It gained 1/2" of brace, and lost a few fps.
37.25 ATA, 7.5" brace (without grip) New limbs are 60-72 (old were 50-60.) Limbs are definitely less prestressed and stiffer.
@ 60/29, 320 gr. arrow - 304 fps., 395 gr. @ 277 fps
With factory 50/60 limbs and 1/2" less brace, it used to shoot 286 with the 395 gr. arrows.
@ 70/29, 395 gr. arrow - 298 fps.
Not blazing fast, but not bad. Best thing is that recoil is reduced and noise? What noise? Much quieter, even without Limbsavers.
I'm pleased.
