If it is a style of bow that you are already familiar with and like, and just want “more of the same, but better,” then you should quickly know if the bow fits that ticket. As was mentioned earlier, the grip is critical, but can be overlooked in the throes of a honeymoon, so make sure the grip is comfortably seated in your hand with no tendency to slip off to the side one way or the other or to torque. It should be immediately obvious to you if the bow draws smoothly or not. Hand shock is something that may not be immediately obvious, but will certainly be noticeable over time.
OTOH, if you are switching to a different style of bow, recurve to longbow or vice versa, or wood trad to metal ILF with carbon limbs or vice versa, then it is more likely that you might not immediately like it, and may require more time to become accustomed to the change.
