blue, which i think is pretty good, when i made a clone a willy i had to use all the rubber every drop, and push the vibrator down in so that i had to use pliars to break the rubber off the cap to change batteries.
i have average girth of almost 6.7" and bpel 8.5" so with this meaurements i am dead line being a white....if the chart is non bone pressed for length then i guess i am purple of course...
