Went fine. Based on a number of posts I found in the forum, I had what I needed. I marinated overnight using Smokin's above recipe (but did not inject), pulled it at 140, onto the grill to sear the outside (5-7 minutes), then foiled with a splash of AJ. Was at 150 when I foiled (did not go higher), 147 an hour later when we sliced and ate. Had a nice, mild smoke flavor (used 3 oz apple), tender and moist. Kids loved it. As Smokin says, not as much flavor inside without injecting, which I'll try next time. Nothing our favorite BBQ sauce did not cure. Come to find out it's not the wife's favorite cut to begin with, so that's another variable.
Anyway, thanks for the input and confirmation on questions. The forum is invaluable and has so much of what us newbies need, if you simply search, read, and try. This was my 4th smoke, everything has come out fine, and I'm sure will get better with practice.
