Hey dude you need to look at the diablo thread that is on this page for the answer to any and every single question or thought that could be asked about the diablo. One quick solution for the skid or motor scooping up debris is to mount it on top. do it. Its easy and perfect. I use two zip ties connected end to end and aroung the edf after I install it same as regular just on top.

The inventor of this idea is called northchim, he should get the credit for it.
