call around to any OMNI fitness stores in your location, and ask about Apollo KBs (they should be getting some soon.) They are cheaper than Perform Better's Power system KBs, and are 10X better - finish, handle size, fit on your forearm, quality, etc. The power max handles are horrible - squarish and poorly finished, with the wrong balance, weight and dimensions for cleans, snatches and jerks. If ALL you do is 2 handed swings, well I guess you could get one, but why waste your money.
btw do a search of "kettlebell" to hear more opinions, but you will be hard pressed to find anyone who posts on this forum with more KB experience than me. Trained and certified by Russian world champion Valery Fedorenko. Not bragging, just giving you a point of reference.
