Orvis, Hardy, G.Loomis, Sage, Bruce & Walker - Expensive, not tackle I've ever bought.
Scierra - have one of their bum-bags, pleased with it, don't know much else about them.
Daiwa - have relied on their gear for years. My first two match rods were Daiwa, my beachcaster is Daiwa, I've a Daiwa seat box somewhere, I've had their reels in the past and recently bought a pair of their Regal baitrunners for tench fishing. Dependable, reliable workmanlike quality at a reasonable price (though I think
their top end reels are pushing the brand beyond what people will swallow)
Greys - have one of their cartridge reels. Good. My perception of the brand is that they are nudging premium pricing with upper mid-range products, though.
Snowbee - I like their lines, but they aren't cheap.
Airflo - when I started fly fishing, some of the earliest advice I got was that Airflo floating lines were rubbish. That impression has, to be honest, put me off them, even though I hear that their other products are fine.
Sonik - I like this company. I like their gear and their business model. I've had three really nice rods from them (four if you include the one I broke which they replaced) and I've been really pleased with the performance to price ratio.
Ron Thompson - I have bought few things from this company, and they have all fallen to bits. My perception of the brand is "buy cheap, buy twice".
Wychwood - my first fly rod was a Wychwood, and in retrospect, it wasn't great for the money.
Shimano - reassuringly expensive. Too expensive, really, I agonised over the Shimano alternatives before buying the Daiwa Regals - the Regals are not quite as nicely engineered, but the price differential was impossible to ignore.
Browning - have an old 11m pole and a match rod from Browning. Think they tried and failed to enter the fly fishing market. Neither the pole nor the match rod is anything more than mediocre.
Okuma - I have one of their fly reels and one of their centre pins. A budget brand with a few premium/niche products, gradually moving upmarket. My SLV fly reel and my Aventa centrepin are both excellent.
Drennan - coarse fishing gear only, I think. I have two of their tench rods and an avon/quiver, and of course have used their terminal tackle for years. Their rods are superb. All of their products are characterised by innovation and quality. If they started selling fly fishing gear, I would find it impossible to ignore.
