BDM & TON/SS - Both these brands make very good top of the line, but their mid tier offerings leave a lot to be desired. Due to mass production of mid/low tier bats from these brands their press is inconsistent. If you are buying from one of the sponsors you are likely to get a top performer from TON/BDM. BDM aerodynamic & SS Limited edition are extremely popular due to their price point, but these tend to have a very uneven behavior from one bat to another. Just because one performed well, you can't be assured that the next one will perform well.
If you are buying TON/SS or BDM from online retails (non-forum sponsors) - my suggestion would be to stick with top of the line models - TON Reserve, TON player edition, SS Gladiator, SS Maximus & BDM Dynamic Extreme.
