When using a string suppressor.... (I.E. MeanV suppressor), does this eliminate the need for string silencers?

Or will it be even more quiet with both?

Yes most likely you'll blow them off anyway !

I took mine off and didn't notice any increase in noise.

I still have some on myn, I don't know if they help, but just habit I suppose.

I usually leave mine on, and just move them out to the speed nocks where any speed lose is minimal and they are less likely to get blown off. Either way seems to be fine.
