Massive amounts of dust.
Even with all that muffling I'm still getting goofy triggering at times so I'm gonna just admit defeat and get a mesh head. lol
I tried with no muffling and it's a clusterfuck of double triggering. Even with all that pressed against the head it still does it. I had the same issues with the toms when I tried to use real heads. The problem went away when I switched to mesh.
Wich is ok with me since mesh is a lot quieter than plastic. haha
But everything sans the kick triggers great.
Oh yeah and that is dust. This is my basement so...
