Next to bat on the AuSable and many other Midwest waters is the Slate Wing Olive, aka "SWO". This #18 and #20 olive may fly hatches in the morning and usually at the end of the Trico spinner fall when that gets going. Watch for the rise forms to change from sipping on the Trico spinners to a splashy rise on the SWO. Check out the pattern at www.riverhouseflyco.com Yippee Tie One On!
