Bottom line is: Find the crossbow that feels the most natural in your hands and that has good balance for YOU. It is an investment that will last for many years so it pays to take the time to choose the right one for YOU! Of course, that’s just my opinion. I could be wrong.
As DJH put it is the correct thing. I would suggest you go to several archery shops that will let you shoot them and try every one they have. After you've shot them all, make your decision.
