How about three jets?
 
I thought about a three jet combo but what would be the best? 
A pencil, fan then pencil?
Fan, pencil, fan? 
Pencil, fan, fan? 
Fan, fan, pencil? 
Would it be better to separate the fan and the pencil or would they perform better side-by-side? 
Would you need to have a fan first or would a brush be better being pencil lead?
