RE: Which of these mechanicals?
In order to give an appropriate opinion we have to know more about your set up, how much much KE you pushin?
Assuming you have plenty, I prefer the Rocky Mountain GatorXP to the Rage as it is Cheaper and is really the original Design and a tougher head IMO.
Those Undertakers look pretty cool, Havent got to try em though.
Yeah AT runs slow sometime, was today anyway.
