Loop-dubbed ungulate bodies & heads make for a floating fly; found them here. Need to test-drive it to see how it floats; may have to trim the underside flat.

hook - WFC Model 3 #12
thread - Veevus 8/0 tan
body - pronghorn (loop dubbed)
wings - sharptail grouse/resin
collar/head - pronghorn (loop dubbed)
