I have a spare wheelset that I don't use. I was thinking of using them everyonce in a while. I was thinking that if I throw new rotors on the second wheelset that the pads would screw up their bedding in. Is that right?
Is it better to swap my existing set of rotors when I use them or can I buy a second set of rotors without messing up the bedding in?

I have 4 wheelsets that I use across 2 bikes and have found it works best to swap over disks and cassettes when changing wheelsets. Not really an issue of brake bedding as it is differences in rotor thickness.

I have dedicated rotors on each wheelset. It hasn't been an issue. They are all of the same diameter.

I have two sets of wheels for my Fatbike which I change regularly.

I dislike even a little brake pad rub and I find these useful: Just In: Syntace 6-bolt Disc Brake Rotor Shim Kit

I have 4 sets of wheels for 3 bikes, all complete with brake discs, cassettes and tyres mounted. Theoretically I could run all 4 sets on all 3 bikes, but I’ve come to the conclusion that I likely won’t run anything but my enduro wheels on my enduro bike, so effectively I have 3 sets which will fit my ARC and F-Podium. Maybe I’ll put studs on one set for the winter, not fully decided yet.

Since you should change rotors if they are worn/have ridges anyways, starting out with newish rotors on both wheelsets should be fine.

I would get a second set of rotors. The more effort it takes to do the swap, the less likely / often you'll be doing it.

I have 2 sets of wheels for both my mtn bike and road bike. Purchased an extra set of rotors for both so that swapping wheels only takes few seconds. Have had no problems doing this. You may (or man not) need to shim the rotor on one or more wheels to match the other wheel set unless you don't mind dialing in the caliper each time you switch. Note, you can only shim outward.

I find it really handy to have the second set of wheels ready to go. Last week I was servicing the road bike hub and ran into an issue that needed parts to get it back on the road. No problem. I threw on the second set of wheels while I wait for the manufacturer to send the parts I need.

The mounting surface and even the bolt torque will change the trueness of the rotors. Also even the same hubs will have slight variations in rotor offset.

Get a second set and true them to the same plane as the first so you don't have to re-center the calipers every time you swap wheels.

Install rotors on all your wheels. As long as all of your pads are the same material (sintered, organic, etc.), you'll be fine. Rotors are cheap, so no need to hassle with rotor swaps.

I never swap around wheelsets, never been tempted to. But I do have a spare rear in case I am traveling and blow up another rear (ended a few trips that way). I keep a spare used but good tire, cassette, and rotor on there. I just have to put in sealant and air and I am good to go.
