Attacking the 6-1 from the spread?

WE will face a team this season that gave us a bunch of looks where the box was a 4-1 but they brought both OLB's, which in essence made it a 6-1. What was weird (unsound) was that the DE's often didn't pinch inside so they wound up with 2 players in the C gap. We had some success with a Zone option look where we would use that blitzing OLB as the read. I really like it away from trips cause of the man coverage pulling 3 defensive players opposite the side we are running to. We also ran the short route from Robinson & Coverdale. Slot runs seam/post & the Split runs a slant. We had some success with quick hitters up the middle but sometimes these OLB's would get there and smack us in the backfield. I am hoping some of you guys who run the spread can help me out here with some additional ideas on attacking this look. I am also investigating the QB trap. Thanks for any comments or help.
