Like many, I have a goto bow.  But I started wondering about backup bows.  If you subscribe to the "if it can go wrong it will go wrong on a trip away from home theory" I'll bet you do.
What I'm wondering is whether your backup to your main hunting bow is exactly the same, a little different (maybe a pound or two more or less draw), or maybe even drastically different.

Mine is 4 inches longer and a pound lighter in draw weight.

Don't have one... my Schulz is all I got

I have 4 bows that I shoot about the same, so any can backup the others.

I truly enjoy the Big Jim take down system, it makes packing 2 bows a charm

I have 3 64" 50# ACS CX, if I'm traveling I just bring extra limbs.

The problem with backup bows is you buy one and it shoots great. So, you buy another and another and   well you know the story.... I keep everything at 52lbs 60" -62" so they all use the same arrows and shoot to the same point of impact.

I have a few that are all around the same poundage, one of my favorites is a Zipper with 2 sets if limbs, both very close in weight.

I have several ACSs as well.  Always take two complete bows on out of state trips. Same configuration, about 2# weight difference.  They pack small. Doesn't make any difference which one I pull out of the case. They shoot the same.

I've got two that shoot (ABOUT) the same.  So close that 'they' drive me crazy       trying to figure out which is the go to and which is the back up...

If I had a wife for every "back-up bow" I own, I'd be Solomon!!!!

So far I've refrained from the backups..did it with guns and all but about 3 just collected dust.

I do have another recurve other than my Sasquatch, a Quinn Stallion. It's about 7# lighter and same length..64".

my 72# Brackenbury is my all around back up but once I get my new Stealth I'll be alternating between hunting with my two Stealths so the one not in use will be my back up.

Varies somewhat.  I make sure the back-up shoots whatever arrows I have for the primary accurately and with good flight.  I currently have the luxury of two bows of the same model & manufacturer only a pound apart but enough years between them that there are notable differences.  But they shoot similarly enough.

For many years my back-up bow was a Bear Kodiak Hunter because it was rugged and reliable.  

I also have a practice of hunting with a bow and then often choosing a different one for the next season.  Though I have favorires that tend to come up in the rotation more regularly.  I never change within four months of the opener or then until the end of the season.  Obviously the prior year's bow makes a good back-up.  Keeps the stock circulating.   ;-)

My bows shoot all about the same and I have three, that will do!

My main bow is a Kanati R/D longbow. My backup bow is also my bowfishing bow and it's a Browning Wasp recurve that's a couple pounds lighter in draw weight than my Kanati. I have altered (added material to) the strike plate on the Wasp so that it has the same point of impact as my Kanati.

I do not have a back up.  Probably should, with my history of breaking anvels with a rubber mallet.

Primary is a #51 Toelke Chinook T/D with classic grip.  Back up is same length, grip, quiver.  Just a few pounds lighter and one piece instead of two.

My first bow is 52@28 62" Pronghorn Longbow my back is a 51@28 62" Pronghorn Longbow.

62" Widow PLIII, 54#@28" is my go to bow. 62" Widow PLV, 53#@28" is my back up....or is it the other way around? Been on two different hunts in Quebec where one of my hunting partners need his back up. So far I have been good, but I am a clumsy old fellar!!

I've used old Widow MAIII's in the 46-48 pound range for many, many years but just recently started using an 40 pound A&H ACS for no other reason other than to keep things interesting and broaden my horizons a bit.  

We'll have to see how it goes for a while but I know that every time I walk past my bow rack and look at that 92' 46@28 MA, I almost feel like I have to say, "Sorry ol' buddy".    If the ACS "sticks", I don't know what I'll do for a back up. Those old Widow MA's were pretty much interchangeable.
