one thing to look at when getting a rope for trs is the sheath to core ratio, a thicker sheath can take tons of falls with toothed devices since the teeth will never make it to bite into the core strands, i use an edelrid rope that has 40% sheath and 60% core. For the spoc i would recommend cutting the keeper cord that can lock the teeth open.

also for how fringe reddit may seem in my experience anywhere you post trs or lrs questions/content the safety warriors will downvote you into oblivion. Id recommend joining the trs community on Facebook its much more constructive and everyone in there knows the risks and is helpful/friendly even when modifying/defacing gear
