[I use the] 19 mm I-tracks with stainless steel wheeled traveller cars with stainless steel ball barings [for] both for my mainsheet traveller and the selftacker rail.
How well does this track need to aligned to the mainsheet load? It can be aligned for mid-travel sheeting, but am concerned it would be significantly out-of-line when travelled out when reaching. What does your experience reveal?
I need to replace ancient battered IYE X-track on my vintage Tornado, and was planning on using Harken BB cars, though this Ronstan might be able to take the Tornado loads:
