Sure thing numbskull , I threw a tequeely which is a very heavy cone head crawfish pattern but it's really a wooly bugger, crazy dad which is also heavy and the meat whistle. At about 50f crawfish begin emerging so it stands to reason they would be one of the prevalent bait patterns to use. Remember though that crawfish are probably the hardest bait to digest so as other species are in abundance I move to minnow patterns and top water poppers, then back to crawfish in the fall as they begin the moot then.
Another few comments I Target rivers and creeks I'm an awful trout guy and I know that as Stillwater heats up cycles move water up and down probably moving SMB to deeper areas as the heat comes on.
Lastly there aren't many Maxim's with SMB they eat where they live so water conditions where you are are more important to feeding than printed ranges in web and print format. Our growth calendar up North is short so when guys in the South are getting SMB on the fly we still have ice on creek edges and snow squalls that shut down any hope of fish.
Tactics: I usually throw WF line on 7 or 8 wt rod with 7' of 10lb-12 mono I want to get the fly down quick and tap the bottom if I can, on a lake I would Target dropoffs structure or weed lines but if you can get to creeks and rivers. Rocky bottoms boulders and slack areas just off current are good spots. Steve Culton is a trout guy up here who guides on the Farmington, he also does a fair bit of SMB and striper fishing and keeps a good blog.
First two are crazy dad the last is the meat whistle and you can Google tequeely fly just Rusty estaz with rubber legs and a heavy cone head.
SMB are easy if you can catch trout you can catch these sunfish on steroids.
