I did this experiment last night with a snowshoe fly.
I tried a super expensive Marc Petticoat amadou patch, a piece of Sham-Wow! (TM), and the tail of my shirt. Also, shirt and gink.
Amadou works surprisingly awesome. It'll dry the slimed thing right out and make it look basically fresh. On the other hand, its like $40. Who considers that a good value? Granted, I didn't pay for it at all, but whatever.
The shirt alone sucks period.
The shirt and GInk works admirably well, but then you can still only do this so much before it just won't Gink no more.
Then there's the Sham-Wow. Its German, and the Germans make good stuff, Vince told me that. Wringing it out in the Sham-Wow was probably 99% as good as the amadou, but at a fraction of the price (well, for me they were both free). Now, that was the blue Sham-Wow, and I know yellow makes objects faster, so I'm unsure if orange makes objects drier, but that's another experiment for another day.
I wouldn't buy one of those amadou patches, until I tried it out. Then I'd have paid $10 for one and thought it was a bargin, until I realized for even less I could rock out with a Sham-Wow.
The MP stuff is flat out stupid priced. Go ahead, ask me about the Wunderbobbin....
