You have to like what you shoot, and be able to get out of your bow what it is capable of or it will be a waste of $$$$
It's like this. You have a rifle which shoots 2 inch groups at 100 yards, but you can only shoot 4" groups at 100 yards. You wouldn't shoot MOA with a gun that shoots 1/2 MOA just because IT can. You may tighten your groups a little, but it won't be significant enough to pay an extra couple hundred $$$$$ for. YOU have to be able to do it. If you can't shoot even NEAR what your gun shoots, then why waste the money on a match barrel, match triggers, re-bedding, etc? Shoot something that fits you and your budget.
