Mike 2, Vicki 2 and , I believe, Musclebound Mike are all basically morph packages in cr2's that link back to the orignal obj file and didn't need a new obj file for distribution. Most clothing is either created new or is a cr2 with morphs that doesn't have a changed obj file. Same with characters, ron. They are morphed versions of Vicki or Michael that are distributed as cr2's that link back to the original obj. No obj file is distributed. Vina is based on Dina, but her geometry file has been reshaped. The pcf file is a way to give a price break on Vina to previous purchasers of Dina. If you don't want to deal with a pcf or don't have Dina, you can buy the stand-alone version.
