Off the beaten path..... Ultima?

OK, I purchased a blue print from BCC Orlando for a 300 series rigid frame and been considering an Ultima drive train (El Bruto) 127ci.  This will be my first ever chopper  build and would appreciate any input whatsoever... Thanks.  GT.  
Pipe fitter's rollem' over on a 45* then two hole the hell out of em!

I used a 96 ci S&S in a rigid frame for my first build. What I have found is that I have a lot of unusable power. This could be in part to my riding style. If I build another rigid I will go with a stock harley 80 ci and baker 4 speed. Ultima drive trains are really priced great. I have a friend who used the 127ci El Bruto and ultima drive train in a twisted choppers kit. Quality looked real good and no problems with it.  

Hey what's up its Don, I love my drive train set up (ultima 127 with a ultima six speed). Havin the power there when you want it is awesome and that sixth gear is insane... just my two cents but, I would go big because if you don't later on you will wish you did... good luck and any questions let me know.... later bro
