Now you mention it, I've had a couple of Dominant stings break on my violin and that was just being stored on the wall (I hardly ever play it. I can't stand listening to myself with the thing so close to my ear

). Shame 'cos the bass strings do sound nice on my EUB.
I've never tried EPs. I have got Obligatos on my Roumania (sic.) carved bass and I like the sound of those very much, esp. arco.
