V4 has a zillion morphs, most of which I seldom use and a bunch of which I never use. Such as the male morphs and and the stock facial character morphs and many others. Is there any harm in deleting these from my working copy of V4 in the interest of slimmed-down scenes?

My understanding is that the more morphs that are loaded, even if almost all of them are set at zero, the more it bogs down performance. Is that correct? If so, I'd like to have a copy of Vicky with as few morphs as possible, if there is no danger in removing most of them. I realize the ones that control joints etc. shouldn't be touched. But if I never plan to use Breast Implants, for example, why not remove it from my working copy of V4?
