Anyone ever use something like this.  Legal in the zones????

I've used those prop blades on smallmouth flies, they worked to some degree, but I didn't notice a large improvement.  Adding on the safety pin Colorado style blade did. The kind you use with Mr. Twisters or Beetle Spins.  Those props only work when you actually strip them or they are facing downstream, so they are not very effective, or not more effective than a flash added into the fly if you are swinging them.  Over the years and with LOTS of observation and trial, I've learned many ways to strip flies in to imitate different food sources. On the other hand, almost nobody uses stripping techniques with steelhead flies. They seem always to be on the dead drift or a swing with only mends and current to impart movement. One warm winter afternoon I had good luck stripping a crayfish fly in 6" jerks with pauses the way a cray usually flees. Noone was around to accuse me of trying to snag.  All I can say is, it's worth a try, Clint.  For the early aggressive steel it may make a difference, the same with droppies.  As long as the fly doesn't exceed 1/8th oz. with the blade, there should be no problem with it. The propellers don't weigh much, and with plastic beads you could keep it under the limit. Thanks for bringing it up. If it works, expect me to steal a few out of your box.

Did not tie them just saw a pic on another thread. Yea the Mr Twister ones would probably work on too. Will look up to AS to see if the have any there. Like you said can't hurt especially when nothing else is not working. My thought too on early and drops

With out re reading the zone regs , I think adding the spinners/ propellers is a NO go

Yep a no go, just checked the regs.     Outside the zones.................    Still may pick up a few to play with.

Nope my bad, looked it up. As long as its attached to the fly and not the leader/ tippet and over 1/8 you are good .

Charlie gave a good description on how flies are used and fished .

Ah on the line above the fly...........    Well still gonna check in on some. I know I have the Mr. twister kind that I think attach to the hook eye so they would be ok.

The regs I read did n't address the metal added to the fly but I really think that spinner is now making the fly a spinner and not a fly,why not run it by your DEC neighbor?
However the way I read the regs it is permissible to weight the fly and then add 1/8 ounce to your tippet if you wish.I believe a weighted fly is the lead wrapped onto hook,not hanging from it.

Ok I am out of work and bored so I looked up everything.
Artificial fly
Artificial fly means a hook with no more than two points dressed with feathers, hair, thread, tinsel or any similar material to which no additional hooks, spinners, spoons or similar devices have been added
 
Spinners are out in the zones
 
Weight
 
Between September 1 and April 30: the use of supplemental weight is permitted with the following restrictions.
- The combined weight of any supplemental weight and fly may not exceed one-eighth of an ounce.
 
So technically an 1/8oz split AND a fly of any weight is over the limit, because it is a combined weight. From what I have seen though,  officers just look at the split shot on your line. If you got a little lead wrapped underneath it all they won't get the scales out.
