I run my TIs on a 70s Aria P Bass w/ a Bartolini 8S Pickup , and the action is medium to medium-low. I tune down a 1/2 step on that bass & don’t ever find myself fighting the strings or thinking of them as “floppy”. They’re almost identical in Tension to the DR Sunbeams I ran for ages.
I haven't tried the TIs so I'm curious what the gauges were of your Sunbeams.
