I currently bag 5 putters, all KC Aviars. I also throw a Champion Dart in the mix on a couple local courses. I strongly believe in using only one putter for putting duties. If I carried 7 discs or less, I'd still carry 2 putters. I'd use 1 for strictly putting & 1 for drives/approaches. I'd choose a stable (straight) driving putter. That way I could make it finish left, straight or right. I'd also make sure my driving putter was in premium plastic so it stays a straight flyier for along time. No need for a beefy driving putter with so few discs in the bag, power down a mid instead.
