For the OP, unless you have odd size curves, why not just use Gargraves straights and pre-formed Gargraves curves. This way there would be not concern of kinking the smaller curves.
My old layout was Gargraves track with Ross turnouts (23 or them!). No problems with any of it.
I think you will find that Gargraves is very easy to cut. When I first did my layout, I cut the track with a Dremel. As I changed things, I went to a cut-off tool with a larger cut-off disc.
As we are now in a rental house, I currently have Fastrack for a large carpet layout with O-84 and O-96 curves. If I build a permanent layout in our retirement house, it will be all Ross.
