Hi Sonny,
I'm not a bloke, but what about one slogan specifically for the "girls" (ie. wives, daughters, lovers, friends, mums) of men here? I was thinking of something like, "Support prostate cancer research and save our men" as one for the ladies (and men of course!). Just an idea since you are playing around with ideas. I also like the 5 in 6 one too, and would certainly wear it too! All the best to you. What a great hobby. Good luck with it. Lana (with CJ).
