tri-comps are good
I have ridden the fortezza tri-comps for a couple years and just love them. The difference is the SL's dont have the puncture protection the tri-comps have. the tri-comps are very fast and a good riding tire IMO 110psi front and 120 psi rear. Im sure the SL's would be a touch fatser and may ride ride even better without the puncture strip in them. They last long for a race tire, I rotate them and get about 2000 miles a set. i only got about 1500 miles on michelin pro races. Hope all this helps.
