I'd build what I'm working on now, a Dynacraft West Coast Limited with a Morini. Only thing I'd do is get a water cooled Morini
The streched crusers are just too long for me. I have capsulated adheasions in my shoulders and just cant reach out that far for any length of time. The Schwinn Choppers are just too small as is the LA Cycles BigMo I got. I would have had to cut and weld the crap out of it to make it fit and the LTD is a perfect size for me.
...altho there's a set of 26" x 3" rims in the yard sale section that sets my mind to spinning...I could build my first bike from those.
