I voted for the vamp because I am in love with Tantus toys, and the throb doesn't do it for me. I was looking into getting the throb, mainly because I love texture, but it seemed to have a few problems. First, it is a little small at 1.25 inches, which is less than the medium size you requested. Additionally, the veins seem like a pain to wash. The vamp looks like a much better choice for what you are looking for.
