Rocketman, although he is rarely posted. Ben Burns and Akmens are talked about a lot as well, but their ROI is very poor and barely positive lifetime if you look at who2beton and track all the plays unit for unit. I personally flat bet all my plays, so the latter two are of very little use to me since the ROI is so poor with such a large range of units they play their games for.
Dr. Coygle is known to be fairly exceptional on hockey totals, but I haven't tracked him personally and can't verify his record on anything other than his 12* plays. Maybe someone else can verify his other graded plays.
Dr. Canada is also posted here regularly by Steve and has been talked about in a good light by many people here, but I have not tracked him myself. He posts all his plays as equal (same units), which is a sign of integrity, so he may be the real deal.
To recap, Rocketman (all plays) and Dr. Coygle (12*) are the only ones I'd bother looking out for in terms of touts that are regularly posted here with Dr. Canada pending.
