I've heard from a couple skaters who tried out the Coro Ace and MK Pro Lites that they aren't really comparable to the regular Coro Ace and MK Pro. One skater who had been in Coro Aces for years told me that the Lites felt significantly flatter, like they didn't have the same profile. Both she and another skater told me that because the Lite blade is thinner, their edges felt very different, and that changes of edge in particular were a huge readjustment. Neither of them felt like the tradeoff in weight was worth it.
