Rhyzer 48 is the closest any company has come to Tenergy 05. My only complaint, which is also true for 05 is the durability. I get about 20-24 hours of hard multiball training before the topsheet dies. Considering that it is significantly cheeper than Tenergy with the same durability, it makes it a much more affordable option. If you are like me and hate the overpriced Butterfly marketing machine, switch to Rhyzer 48, you won't be disappointed.
