I just picked up the 6.5 varmint, I love tikkas. I'm also interested in putting a sterk handle on mine, post some pics when you get yours installed. Nice setup!
I'm also considering 15x for hunting and spotting. There were a pair of 18x at the last 600yard match I shot. It was way easier on my eyes spotting through the binos rather than the spotting scope.
I shoot my 22 all the time. It helps me practice stable positions on baracades and weird shooting positions. Like the others have said, it's cheap and no reloading required.
I have a gen2 PST on my NRL22 rifle. I absolutely love it. I agree with the terms stop, it's nice to have. I was using a diamond back tactical before. It's good for what it is, but the PST is awesome.
Just bought a tool bag from harbor freight. Figured I'd get one there to try out since they are pretty cheap. So far I like it. Keeps my stuff organized and it's way easier to find stuff than in a backpack.
Good luck with your barrel, I want it see it all done. The few I've seen with new barrels look great. Even with the barrel swap and stock swap I don't think your in the voodoo price range yet. Is that true?
