Totally dude, just do it once, even if it takes longer to save up the cash. You'd hate to have to hear "I told ya so". Go 1 ton from the start. I did exactly what your doing (kinda) and learned the hard way. But I did it by trying to build the burliest baddest toy axles. No matter how strong the shafts are, the achilles on a toy axle is the 8 inch r&p. So I tossed everything and built a 14b and a 60. I spent soo much more money than needed since I did it all twice ya know.
