Are you sure 1100lb is enough working load [for a Tornado mainsheet traveller car] ?
I've been assuming crew can supply 125lbs. For the 9:1 that comes stock on a new T, that's 1125lbs of traveller load, which is a pretty good match.
Wouter's recollection of measured T loads is reassuring.
The alternative a Harken 2736 or 2737, with 1250# SWL, and 2500# breaking strength, compared to 1100/3080 for the Ronstan.
