Re: Friction v.s. Chain
I use both and will admit for a hilly area I would go with belt or chain drive. My friction drives are fun to build and great to get a little exercise but If I am going to the store which as a couple of nasty hills I wouldn't even consider using friction drive. Then again I built them maybe one of the commercial ones is better.
