Depends how much I over-do it.

More seriously: I needed a lot less rosin on my Spiros and Evah Pirazzis than I need on my Silver Slaps.

yh im playing on silver slaps, the effect of the rosin is gone within 10-15 minutes of playing

I was told that there is enough rosin when the hairs feel sticky to the touch. Do this: lightly depress the hairs with the pad of your thumb, then take your thumb away. If the hairs feel sticky, there's enough rosin on them.

(I was [b]also[/b] told not to touch the hairs with my thumb/fingers ).
