Ahrex are osprey doublesI like the shape of the Patriots - when they build them properly. I think the wire is a bit thick and quality control is shocking. There’s often a real difference between the colours too, in terms of wire weight and shape.
I like the shape of the new style Partridge Heavy double, the quality is more consistent and the weight of the wire is better than the patriot. I’d like a wider gape though.
The FM Magni and the Veniard Osprey have longer more traditional shanks and seem like good, strong hooks. I mostly buy these because I know what I’m getting and haven’t had any problems with hook hold in the sizes I normally fish, 10-14.
The Loop doubles are very consistent in quality and are very strong hooks. I think a Shrimp fly looks great on them, but for some reason, I can’t get on with the look of longer hairwings on a down eye hook.
I think the Ahrex progressive doubles are spot on between the Patriot and Magni, but they’re ruinously expensive.
