I think you're onto something. The thing with my game is that it's still far from watertight, and I'll always make 1 or 2 substantial mistakes per session. The difference between the limit games and no limit games is, in NL, one mistake can cost me my entire stack - in limit, I have a buffer that protects me from myself, so to speak. I think my limit game is OK for the levels I play at - I'd describe it more as a diamond in the rough (if I'm being generous to myself), and still needs a lot of polishing before it becomes a true thing of beauty, whereas my NL game is still pretty much a lump of coal that needs a lot of time and energy exerted onto it before it even has the potential to be a gem (I know - I'm pushing the analogy to its limits here).

Whilst I will remain playing mainly LHE ring and SNG's (which I also fare pretty good at), I'd like to sharpen up my NL game to the point where I can at least play at some profitable limits. I've got a long way to go with that, but this place is really helping, so thatnks for your advice.
