1. is disc brake available? if not, don't consider. if so, continue
2. what size tires will bike take and what size do I need for local streets?
3. is bike designed to carry my stuff on commute?
4. how much does the full bike weigh?
5. how did the bike hold up for a 4 mile test ride?

---------------------------------------------------------------

1) both can have disc brake brazeons added
2) the sport tour will take up 25 with fenders, the cross 35 with fenders
3) both can take a rear rack which will allow me my panniers and/or trunk
4) Sport tour around 20 lbs, Cross about 22 lbs.
5) both are custom built so cant test either

I guess its a choice between longer chainstays/wheelbase on the tour vs higher bb, wider tire options, and an extra lb or 2 on the cross.
