I have been using code 80 in my HOn30 ventures. The flextrack is a dream to work with and the turnouts seem to be very high quality. Most of all, the price is easily half what you'll pay for others. I did try code 50, which looked great, and my minitrix bounced ahppily across the ties like it was a gravel road
I think it would be OK with most newer stuff, but I just switched to 80.
Also, when discussing name brands, some brands that have bad reps in HO have very good reps in N, so don't listen to us HO guys
You may hear terms like buttman, or deathlike, which do not apply to N.
BTW: A&JRR, welcome tothe-gauge, I'm in Lafayette.
