Options abound for spey reels. For the classic look w/ disk drags - Bogdans, Saracione, Janciuras reels (good luck finding one of these), Olson, Noel, Loop Classics, Peerless, Godfrey, Herman, Vom Hofe. Bring your wallet!
A much mojo option is Vlad's VR Design - Avro Lancaster 4/0 Titanium Fly Reel (just to get you guys drooling this morning).
C&P's reels that don't click on the retrieve.... the only one I know is Farlex. What fun is that?
Tim still makes one heck of a reel in multiplier and outgoing/incoming clicker.
Vintage C&Ps for spey rods include Thompson 500, 3 3/4 - 4 1/4" W Hardy Perfects (my fav), Farlow Perfects, Dingley Perfects, 4" Uniquas, even the larger 4" Hardy St George or 3 3/4" St Johns (or other copies) are all good options.... however.... you have to be careful as some of the older reel feet or too long on new spey rods. There's ways around this like making a new foot or filing them down (*gasp*!!!!).
Price conscious older C&Ps include J W Young 4" Beaudex, Pridex, Freedex or Beaulite or other series from 50s-60s (1540s). Farlow had the 4" Ambassador, BWP, Aquarex and others spey worthy that all fit modern reel seats.
New world or recently out of circulation spey sized reels include C&P or Disc - Leyland's Classic Spey Series, Abel Spey, Hatch, Nautilus, Ross S3, Orvis Battenkill, SA System 2s, Martin Big Game, Valentine, Hardy Cascapedia, Marquis, big arbor Hardy Ultralite 9000s, or an all time favorite the Pflueger Medalist 1498s.
Or even the cork drags - Tibor Spey, Saracione Monarch... these are rarities to find. The Tibor Spey is for big stick - 15 fters.
Prices - $35-$3000 ......
So many choices..... not enough time to fish. I fish in my head more than I do in real life fortunately.
