To be honest, those two are my top contenders. It will boil down to the test ride. Only thing is, the Marin is available through the local Sun & Ski, which is waaay out of my normal travel corridors. All of the other models can be had through a couple of different shops that both have 2 locations each. The LBS that has the Trek and Redline is like a 10 minute ride (if that) on a mix of street and MUP from the LBS that has the Kona and Felt. So all but the Marin could be test ridden back to back along a route that I know and very closely simulates my everyday commute.
