felt frames

[rjm]

I see Felt makes many models ie chief,slater, harley D ,mango and another that looks like a yamaha dirt bike. I've only ridden the slater -it sold me on the frame geometry for my build. Are all of these frames the same geometry? I would rather build from a used bike (cheaper for me and better to keep us enthusiasts cash flow rotating amongst us) Any help for noob is appreciated. also anyone have one of these f/s ok to pm me thanks rjm
