Funnily enough I think it comes back to balance. Big stiff rods need bigger hooks to stop them being ripped out and light through actioned rods need smaller lighter hooks. In general I think small sharp trebles hook much better. I also think moving the fly quickly leads to much more positive takes (I also think it leads to more takes but that's a different topic). If you try a grab a 14 B990 out of a box you will see why I like them.Partridge for me too, a great lover of the X1 and the sadly discontinued X4 too.
I'll also second the Guideline terrible's too, well apart from the price that is!.
Careful in what you ask for in a strong treble.Modern rods are a lot lighter in the tip than they used to be and certainly getting shorter too!, I'd question the need for a really strong terrible in the UK, and certainly question the ability of these "strong" hooks to be consistently "set" correctly.
I've still a good few Rob Wilson extra strong terrible's by Partridge in my kit, when I line them up with say an equal size 12 X1, they indeed look strong, but nesscessary?.
My approach revolves around smaller lighter demon sharp hooks, even sacrificially so.If the hooks damaged after unhooking, well it gets chucked and a new one tied in its place.
Bear in mind the issue of straightened hooks in general is largely down to them not being set correctly in the 1st place.Most hooks can be opened out in the hand by sheer finger pressure! if you do it the right way, however set them down to the bend as they should be set and its a different matter..
Maybe getting Salar to take our flee's in a right manner(good positive takes!) will alleviate poor hook holds.Some of Rotenone' s thinking on his flee's may well guide here!.
Little fresh thinking perhaps?.
