Nice bugger. Weight might be an issue, but casting and casting well are two different things. Flipping these out from the bank might be all you need with a 9ft rod. Now if you’re looking for a big double haul cast… try not to ping it off your rod… I’ve got a 7w on its way to TFO, I’m speaking from experience.
that estaz looks pretty bushy but I’d still try and wrap the hackle feather from the tail to the head instead of just a collar. It helps give the fly more body and taper. Looking good tho! Report back on how it goes.
