I've got the Spinerval dvd's and enjoyed them (as much as you can enjoy cycling indoors) last season....toward the end of the season got the Carmichael ones...jury's still out on those. I think I'm going to ride with the Tour dvd's this season - my SO really likes riding with the pelaton, so I'm going to give it a try. No matter what, it's still INDOORS, and not my favorite...
