I use HEM2 and find the information I get from it to be invaluable. When I was playing alot on lock poker and had alot of tournament hands built up on some of the players I saw alot it helped with decisions based on trends opponents had. I think it helped alot in my decisions to reach the FT of the $55 5K 5 times in 1 week period and is 1 of the best investments I could make into my online game
