Sorry; I was thinking of the RS77s. The Roto SM77's tension is listed on Roto's chart as 178.57 lbs. total. Which, while not nearly as bridge cable-y as the RS77LD's on my Gibson T-bird (214.41 lbs.), is, IMO, either at the top of "medium high", or the bottom side of "very high". They pull 35 lbs. harder than the TIJFs do, in any case. Personally? I'd consider the Fender 9050L's to be a much better substitute for the TI's. An Eastwood Magnum Bass (with 9050Ls) is an unlikely A/B comparison with an Alembic Epic (TIJFs), but, to my ears? They sound surprisingly similar. The 9050L's tension is no worse than the Roto SM's (probably less, actually). And their tone is remarkably similar to the TI's. Maybe a little more bottom end, and a little less high end, than the TIs, but... pretty much the same. I had them on my '78 P-Bass (with the Jazz spec "A" neck) for several years. Never a problem, neck-wise. They'd be there yet, but I wanted a more "vintage" P-Bass sound, and the GHS P-Bass Flats are as close as I can get to the original factory Squire Flats sound. So, it wears those, now. Oh, and before the 9050Ls? For the first 8 or so years I owned it, when it was my only bass, it wore those bridge cable RS77LDs. Never had a problem with those, either...The SM77 I have installed on my jazz bass, with its highly sensitive neck to high tension strings, don’t feel like bridge cables at all.
Somebody in another thread suggested that they may be considered a cheaper alternative to TI JF344 and I have to substantially agree with this statement.
