Sounds fine to me. The 307 is only about $15 bucks more and advice given is well taken. The 307 is a bit longer and the bowl is deeper which both is a plus to me. I like one with a bowl depth of 1.5" or more but that in itself is not a deal breaker.One day when everything is settled down we will have to meet up at Smokys or something and smoke a bowl together.
Oh and Herbinedave knows his stuff. He is probably right but it does cost a lot more so take that into consideration.
