Since you already have the Stumpy trail bike, sell the Sentinel and get some sort of Enduro sled. Spire / Enduro / whatever looks sexy at the moment.
That said, I like the 38 better than the Zeb. The Zeb's damper is a bit more tunable, but the 38's air spring is way better, and that wins out in my book. No experience with the 37mm option, but I hear it's nice.
