It isn't a Rapala but I fish Priest for Hybrid Striper and Stripe every year and this fly produces plenty of Stripe during the spawning run. Fish it on a sinking line for best results.
This Chartreuse and White Clouser is another great fly for the water Zebras and Stripers.
This guy took that same Clouser.
The Hollow Fleyes are great when the fish are keyed in on larger shad. http://flyfisherman.com/northeast/ds...ye/index1.html
I'm glad to see some other FF out there looking for the Stripped bite.
