I went to the local archery shop with the intent to try the entire selection, but I fell in love with the Bow-tech Assassin and never bothered with the rest of the selection (so I will never know). They shop owner did offer; and he let me (nearly forced me) to stay a while and shoot the bow-tech before I paid/ran out with it.
I was easily-sold partly because my first/previous bow was a 1992 Bear Kodiac that fired arrows like a mortar
The weight; stand around a while in the store with the bow in your carry-hand, say 30-40 minutes.
The let-off; get in front of a target with an arrow knocked and see how long you can hold the bow in the drawn position.
Start off with a dozen arrows; use 6 for practice and save 6 for hunting.
X2 on the information in the previous posts; especially the draw-length for the bow and the arrows.
Lastly, a rule to consider is to never accept a full-priced bow off the demo-rack; it could have been dry-fired by previous customers.
Any contentious counter-person will/should understand if you do not want to pay full price for a "demo". (Dry-fire=bad)
If it is a demo, look closely at the sides of the limbs; you may find tiny parallel lines (cracks in the paint), that is an indication of dry-firing.
