I do at times  

I do have seceral bows read to go at all times and I do shoot them interchangebly. Still I do think it is good discapline when you are developing your shooting to pick one - at least for a season. Season meaning "early fall archery season" for example - then switch for late fall/winter IF you think you will shoot better with a different bow - stay with the bow IF you were high recovery sucessful. Very confident accuracy comes after considerable time invested - talking years now at least for me. Although I have been shooting bows since 1970 I don't think I was "confident-very accurate" until the early 90s - certainly you can expect to learn much more quickly with all the information and skilled poeple to learn from - but I do think you will learn better on your one best bow worked at a time.

Yes I like switching. They all need a chance in the field.

I do on occasion, too. On thing you want to make sure is that whatever you use hits where you are looking. You don't want to be thinking about making adjustments during the stress of having a deer right in front of you.

I'll typically switch as winter cold sets in. A lighter draw weight works better for me during a long, cold sit.

I use a couple of different ones during the season

Got six on the rack and they all get used, just depends which speaks to me on any given day. They all shoot the same arrow so no problem.

I shoot a half-dozen different bows during season, recurves and longbows.  I might switch bows during the middle of the day.  Really doesn't make any difference.  My bows are fairly close in weight, as are the arrows, and there's absolutely no problem in switching from one to the other.

I have two Kanati longbows that are the same in everything except wood color. Whatever color I feel like using that day.

I have way too many bows so if I harvest something that bow gets hung up.  Sometimes it Never comes back off the wall if it was a special moment...like a black bear with my own Osage selfbow & stone point or a friends Northeast Woodland Indian hickory bow with my first Team Tippit broadhead buried into another black bear!

I have too much fun hunting to be tied to one bow  

I usually pick one before the season (one for deer, one for turkey, one for small game, etc) and stick with it throughout that particular season....unless something shakes my confidence or otherwise makes me question the choice.  Then I usually go to my tried and true Jeffery Royal Hunter that I have shot since 91-92...it is like a comfortable shoe.  

I have 6 bows that I will hunt with (the others are my vintage Brownings that are little more than wall hangers)....I like rotating them but once I get into hunt mode I like the consistency of same bow throughout.

I keep my 48" bear Mag. for hunting from a tree, from the ground I'll use a LB most of the time, just don't know which one but they all work.

Bob lee recurve 52# 600gr arrow bear rest for moose.BL 48# longbow 480gr arrow for deer,both bows shoot the same for me.

I build wood bows so I shoot lots of different bows each year. About a month or so before hunting season I stick with one bow that I plan to hunt with. I always have a backup that shoots similar to my go to bow and practice with it enough to know where is shoots.

I may shoot 5 or 10 bows in a years time , most for me now days are Bear TakeDowns in one form or another with all the limbs and risers I have I can shoot a new bow every week. From short to long light to heavy dont matter they all shoot good for me with just a few arrows shot.
When I get out my HH BigFive it takes a few doz shots to get in the killzone for a hunt....

I have in the past,but not anymore

I use them all. They all have very similar arrow casting. Some faster,and use a heavier FOC,but the all shoot there respective arrow in very close trajectory so my aiming is the same.

During our winter indoor 3-d league i'll shoot all my bows. I have 4 bows at the present time. But for huntig season i usually stick with one bow. For turkey season it's my 54" RER Arroyo out of my blind. And this fall for deer season it'll be my Robertson Trybal Styk that i can't wait to get into the woods.  

Two Big Jim longbows and one Fox longbow all the same poundage. No problem switching them out.

I hunt with all of mine.  I hunt with a different one in the morning, afternoon, and evening.  I have too many favorites to not use them.
