Shooting lots of different bows is lots of fun.
But as the old saying goes, "Beware of the man with just 1 bow".

Lots of bows, sometimes too many.  The older you get the more you realize you don't need them all, you just need to be able to shoot at least one, lol.  Merry Christmas!

Yes the best thing is to stick to a single bow and arrow set up.Said that I shoot at least 3 bows a day and at least once a year everyone of my 70 bows.At 20 ys is not a big difference.

Find a bow that you like and stick with it. I think, a person really learns shooting characteristics of himself and a particular bow. Both can be maximized without confusing the brain.

IMO, if you understand how different the bow shoots and mentally prepare yourself before shooting it your body can make those adjustments in a few arrows.

I do think it is important to practice with one bow at least two weeks before hunting season. The more confidence you have before hitting the woods the better.

I have several recurves from 58"-62" but all are +/- 2 lbs draw weight. I shoot the same arrow with all. I don't have any issues switching between them, in fact, I grab the bow I feel is best for the situation I anticipate...

Have a few bows the same weight and am surprised to hear that some can adjust so quickly. Each one seems so completely different. Have tried alternating bows in the same session to gauge the variations but have found it beneficial to stick with the one for the session or a couple of days before trying another and repeating the process. Perhaps the volume of experience allows others to adapt so well
