Euan,
I will include this card in with the samples, simples!
As discussed in a previous post there are many options and a range of similar hooks but I'd say these are my ones.
I was advised to bend the niche hooks in the vise by Peter Smith and although dubious, I had many fish on these without incident. I suppose it could work with any of the emerger/ living larvae hooks.
Re last post - Ben advised me a couple of years ago to tie smaller/ shorter patterns on longer / larger hooks and it is now a firm favorite method , being able to fish the size of insect that I wanted but without the worry of finer hooks.
I'll post them tomorrow.
