Well back in the early 90's I met and hung with Tiffany Mynx in San Francisco for a quite a while (interesting chapter in my past) so I hold a special place in my heart for her.
all are physically 10s but the difference is performance. i think sara has great energy (at least used to) but doesn't push the envelope. lisa definitely pushes the envelope but isn't always very energetic. tiffany, has the entire package. pushes the envelope and has more energy than both lisa and sara. tiffany mynx wins for me
