Some used to try and cram full length Ox springs (plus others) in the cause of meaningless and gun-spoiling power crusades back in the late 70s and 80s. Some were more enlightened and tuned for accuracy and pleasant shooting manners instead. The power chasers gave the Ox a bad rep. To the point where, even until fairly recently, some would say they're only of use on a garden gate.
However, when you get highly knowledgeable and respected tuners like T20 and Shed Tuner saying that they're actually okay, and merely need the length adjusting to suit, that confirms for me that, suitably shortened, all should be good.
