RE: single pin adjustable vs. multi pin
Not picking on you, but just trying to give a little education. Shops do not set up and take measurements on bows. They set them to certain accepted standards that work fairly ell with most bows. All bows then need to be TUNED to shoot the arrows you have. That is your job, and if you don't know how then ask and learn.
Measurements are your responsiblity also. The reason you take them is so you can tell if something changes, and in the event you eventually start doing your own work you'll understand why taking measurements is important.
I'll givce you some "sage" advice at this time, being as you haven't learned much about tweaking. Be satisfied with what you have. 242 fps isn't all that slow. It's not fast, but certtainly not slow. And if the bow draws smoothly, is quiet for hunting, and accurate for you then just shoot it. One of the best hunting bows I've had in over 30 years of bowhunting was a Golden Eagle Litespeed that shot 237fps at 61 lbs. But man was that bow ever quiet and forgiving.
