With a total arrow weight of 364 grains @ 311 fps,..calculator gives 78 ft/lbs.

That's enough to energy to hunt T-Rex's.

No reason to change if it's still shooting good. You could buy new stuff, but probably wouldn't improve significantly over what you're already shooting.

I'm shooting an 07 Drenalin getting about 64ft/lbs,..way more than I need for a deer.
