If you search for Sumrall, there are a few reviews of his cues. If you have any questions for him personally, just give him a call @ 806-778-1957.
He is a friend of mine and I know he would be glad to answer any questions that you may have. Or, I have had several cues of his in my hands and could do my best at answering them also. I actually have on that will arrive tomorrow or Thursday and I had a deal worked out for another one that is on hold at the moment.
If you would like, just shoot me a PM with any questions you would like for me to answer.
