The Gator ProGo was the one I was going to suggest as well. I've been thinking about finally replacing my iGig double bag after a good 15 year run, and a friend has the Gator... definitely seems like a well built bag and the way I'll go for a replacement. It's too bad iGig isn't around anymore though. I have a single and a double, and the front pockets are absolutely cavernous.
