my full sized bag fits in a strainer that I bought at the LHBS. I am glad I dont have to mess with more than one bag. The beauty of BIAB is simplicity.
For 5 gallons a single bag should be fine; however, if your not a weight lifter, a 10 gallon batch will be difficult to lift using a single bag. If you are going for easiness then two bags is much easier one.
While two or more bags is an option, I feel one bag and a ratchet pulley can easily handle a keg full of grain.
