Keep in mind that the size of the idler pulley has a big effect on the amount of drag. The idler on that Corsair is tiny—and will therefore produce more drag—compared to the 18t tooth idlers found on modern high pivot bikes the Norco Range and Deviate Highlander. I've ridden a high pivot all-mountain bike with a 20t idler and it feels quite nice.
