Right now I'm going to have a hard time taking the aliante off the bike, to be honest... but the plan was effectively to alternate until the brooks broke in.
I proofided it a couple of times when I got it, and have now left it completely alone. If I find the Fizik starts feeling lousy on long rides I'll commit myself more to breaking in the brooks but for the time being it's the happiest I've been with any saddle.
