I put some Panaracer pasela tires on the LeToaster a few days ago and also switched to a 19t rear sprocket. Next week the temperatures are supposed to get up to sixty degrees F, so I will be able to shed a lot of my bulky winter clothing. It will be interesting to see how much easier the bike gets to ride when this all comes together and I can move more freely and be more "aero" on the bike.
