I've had the same thing rolling around in my head lately as well. I'm gonna go the 10.5" route, and i know that either of them will be the balls, so deciding is really tough. The wait time on the Noveske's right now is the biggest issue. I guess there are some supply problems on their end with the vis uppers, so everything I've learned points at around a 10 week wait, maybe more. Last time I was on their site, everything with a vis said temporarily unavailable. I am a patient person, but then, I'd have to wait for the paperwork to clear the BATF. With this in mind, I'm leaning towards having Wes at MSTN do a build for me with a Noveske barrel, vis, and switchblock. I've spoken with him and he rules. This route has been getting the most consideration lately. Or I could wait on the 10.5 N4 that Sherri told me they are testing for a release relatively soon. Then again, I've always had an interest in the LMT MRP setups, and there wouldn't really be the wait that would be involved with the other options. I love everything about it, but all the talk about the Noveske barrels has got me wondering how the LMT barrels stand up against them. Any of the above will be sick, this I know. Making this decision is a luxury problem, and maybe I'm over thinking it. I just want to do it right the first time.
