Larry-GO FOR IT!! You only live once...as somebody else said, 'we're all going to be dead for a really long time, soon enough.'
Regarding NS EZ Track, its a very good product; at least the sectional track. I haven't used the swtiches or cross overs as of yet, and have no plans to, either, as they are currently designed. The curves come in sizes from maybe 18" radius, all the way up to 35" radius or so. I have used a good number of their curves in the past, over 24" in diameter, and never had a problem.... I've also used the Kato Unitrak in HO, without a problem either. I've been in the hobby, with one sized layout or another, since about 1975. The Kato, is code 83, I believe, and also has switches and such, besides the sectional track in its product line. From what I've experienced, the Kato track conducts electricity better, or has fewer corrosion, or 'dirt' issues than just about any other HO track out there. I used it on my 18x24' layout mostly for curves, I had from about 2000-2008. Ended up selling the condo where the railroad was kept (in the storage unit), but saved the track, for reuse.
My plan, since Ribbonrails jigs weren't fully available, in 2000, when I started that layout, nor was I good with joining flex track on curves, was to use the large radius sectional track as a slightly offset guide, using the MLR tracklaying spacers/gages, to laying double track flextrack mainline. Am I doing things the same way today? Not sure yet, but 'its later now,' and I want to enjoy at least a portion of my trains, running thru a sceniced layout, in my basement, in this lifetime; not the next. I figure in the next lifetime, either 'all layouts are exactly as the builder/designer/owner imagines them', without all the issues typically found with building a layout in this one; or I'll be shoveling so much coal to keep the 7734 loco running, that they'll be no time to concern myself with which track is better....
