Thanks for the kind words gents. Unfortunately the economies of scale means it's not worth my time to sell; I suspect the same holds true for most local tiers. I did a lot of fly fishing and tying for trout in my younger days and I'm just applying those skills to buckies now. So my suggestion is get the heads you want and take them to a decent fly shop, a lot of these shops tie flies in-house and will be able to create whatever pattern you want for a small fee. That is if you don't want to buy online, which is my first choice.
Also try to reach Grant Marshton, some years back he used to sell bt's, not sure if he still does.
