Loop rods and reels
Tony, be-bopp over to the International Spey Board. Under the sections on Euro rods and under reels you'll see several old threads on Loop equipment.
I'd try to be more specific but don't pick up in your question whether you were just interested in a floater, tips, etc. Huge difference in size of reel you'll need say a DT 10 wt or a 10-11-12 Rio Acclrtr.
But think you'll find your question covered in depth.
