N/A Changing the Red Panda Gen 1 to Gen 2

Have a question, has anybody with the Gen 1 panda get the changeover kit to convert it over to the Gen 2? If so, how is it shooting? Is it more air efficient? The reason I am asking is I am trying to decide if I should do it to mine. It is shooting so well I don't know if I should mess with it. You Know the saying "if it ant broke don't mess with it" True owners' opinion would be greatly appreciated.
