I don't know how anyone could think that Checkpoint is in any way a substitute for a full-on touring bike like the 520. Maybe light "bike-packing" or credit-card touring like they show in the ad copy, but not self-supported solo touring. I like the suggestion to take the Checkpoint, sell it, and buy the REI ADV1.1. Or look for a used 520 or 750 (same frame) or any other real touring bike. At least if you intend to do loaded, long-distance touring. And even if it's just day trips or credit-card touring, if you've been spoiled by riding steel, an aluminum-framed bike may not make you happy.
