Hi Horses50
Welcome to the forum.
All sound advise so far from previous posts but just to add another iron in the fire I get all my capes/saddles from Jim @ jimsflyco.com in the USA all excellent quality and the price is brilliant including shipping.

On my last order I had 5 pro grade quality Whitting Herbert Miner genetic capes for $125 including shipping. They were here in about 8 days. They are excellent quality and came well packaged.
Here is what he says about Pro Grade;
Hebert Pro Grade has the same quality Whiting Farms hackle, the only difference is that the hackle usually has a higher quantity of one size hackle, but still with a wide range of sizes, typically sizes 12 through 20. Some have larger sizes and some smaller.
He is very accommodating and will advise on orders.
You can email him direct from the web site.
He was recommended to me from this forum as well.
Cheers and good luck
