So will a sintered bronze clunk without the worries of having to "massage" the clunk or fear of fibers---There are also other types of clunks that filter without causing fibers to sluff off--I believe that Don's Hobby Shop sells a porous nylon? membrane clunk that works well...Also---Have you guys thought about the vent line for a filter??? There is suction on this line when the engine is running and this line will suck up debris from the ground that the prop stirs up..Have a look...I got mine at Don's Hobby Shop for $9.95--
