Hi there.
First off, I'm going to assume that you're rather tall (over 6ft) because eight inches is a lot to pack with...especially since it's hard to make a lot of prostheses look entirely flaccid. It also seems like an odd option to get without the flex rod, because I think that means it can't be used for sexual intercourse...then again, I could be wrong here and that reelmagik's may be hard enough to use without it. Do you have any prior experiences with prosthetics, like enough to know what may be too large and small for you?
I sport larger than most guys here, but know I could never get away with eight inches, so this may explain why I'm so inquisitive.
