I am going to build a staging area on the lower level of a new layout. I am planning on using code 100 track but may switch to code 83 for the upper level becasue of looks. I have some questions: Has anyone used Model Power track and if so, what were the results? The track seems like a deal at Trainworld. I could save some cash at least on the staging yard by using Model Power track but don't want to find out that it kinks, is out of gauge, or has other problems. Do IHC and Rivarossi pizza-cutter flanges work on code 83 track? Does the mfg make a difference if it works or not? The kids and I have some older stuff we just can't part with. Any comments or help is appreciated!
