What about the sticker foam indicators?

I used biostrike but didnt like the residue it left on my leader. Is there an easy way to get it off? I switch between drys and nymphs in a day so that residue was annoying!

I do like using a large dry as the indicator.

Sad to say, there isn't a way (not that I have found specially in warmer weather).
Use the yellow and the red and you end up with kinda an Urban Camo LOL
