i don't think that is the case at all, actually there are very few carts. out there, that are so light, that they would require a headshell weight, the Dyna. 17d2 being one of them, i use the 17d on my scoutmaster with the headshell weight (which vpi sent me free of charge btw) and it works very well. anyway, just wanted to throw my opnion out there.
