I have no idea how well a barrel will fit in the racks I have, as I only have 10 chips. But I'm sure Apache will be able to recommend something (assuming it's not in an earlier post).
I stand by my earlier statement...for the price, these are fine china clays. None of my samples are perfect. Your preference will depend on what you like.
I can fit 21 Majestics snugly in these racks:

None of my (almost) 500 chips are perfect either, but they are a great value for the price IMO. They should hold me over nicely after selling my PCRs until the bug bites me again and/or actually start hosting games more than a couple times a year.
