Pretty much what Bob said. Slow it down, open it up, kind of lob it out there. To top it off, I like to really drop the rod tip at the end of the forward cast. That helps me accentuate the whole slow down, open up, lob it feeling to the cast.

OR you can go up to a really fast action 7 wt and throw tight loops with big weighted stonefly nymphs ( 2 ) under an indicator.
