I'm looking to make my 1st order of F/T mice for my BP. From what I've been reading, it sounds like you can't go wrong w/ Perfect Prey or Big Cheese. I was looking at feeder weights and there seems to be quite the range in sizes. For instance, adult mice are listed as 18-32 grams so using the 10% rule, they would satisfy a snake anywhere from 180 - 320 grams. Would I need to feed more then one of these to make up for the difference or am I makeing this too complicated. Meaning should I just sort them from smallest to largest and feed the smallest ones 1st?

As info, my BP is 260 grams and has rejected rats so I'm either going to stay on mice or try the switch again once he puts on some weight.
