You're more likely to cause wear my tracking a stylus too light. If the stylus bounces around and loses constant contact with the groove, that's when you're more likely to get damage to your vinyl (and it will probably audibly mis-track at that point). The reason tracking weights are heavier for a DJ stylus compared to a "hi fi" stylus is the suspension. On a DJ stylus, it's designed specifically to track heavier because it's an environment where there's much more likely to be physical interference (for lack of a better term) with the playback system. They stylus is much less likely to jump out of the groove at 3 grams than at 1.5 if the platform that the turntable is on gets bumped. A DJ stylus not really comparable to the old heavy arms with crummy bearings and sapphire needles from the 50s and 60s (and those typically tracked at 5g or more). It's more comparable to something like a Denon DL-103 where the tracking force is in the 2.5 gram range. My guess is that your N30E would probably do fine at that VTF.
