Hi Dan,
Firstly, good on you for taking the plunge in to flytying and what a great first effort - way better than my first attempts that all had massive heids, though I was only 12 !
Others on here have waaay more experience of fishing the Don and will have some good advice but here is what worked for me last year and what I will be going with next season:
SpidersWaterhen Bloa (Apr, May, Aug, Sept) Size 14
Snipe and Purple (Apr, May, Sept) Size 18, 16
Grouse and Orange* (Apr, May) Size 14 (* used Pearsall's 6A Gold not 'orange' !)
WetsBloody Butcher (only when targetting Sea Trout) Size 14, 12
Black Pennell (as above) Size 14, 12
DriesJT Olive ( Apr, May, Aug, Sept) Size 19, 17
Olive Paradun (Jul, Aug, Sept) Size 16
CDC and Elk (May to Sept) Size 17, 16, 14 and 12
Wyatt DHE/SHE (Aug, Sept.....but could use all season ?) Size 18,16,14 and 12. Technically an "emerger" but counts as a dry in my book.
Balloon Caddis (Jul, Aug, Sep) Size 16, 14. I use a 'variant' that hackles CDC on as a thorax so techically a "Balloon CDC and Elk" - I like the way the foam head 'flattens' /lowers the wing profile more like the insects on the water.
Tan Klinkhammer (May to Sept) Size 20, 18
NymphsPTN (all season) Size 16, 14
GRHE (all season) Size 16, 14
Czech Nymph (Apr, early May) Size 8, 10 ( in colours to imitate Ryac's and Hydropysche's)
The only thing I can think of adding, following my reading of R.M Neill's study, is something small and black. I tried Stewarts Black Spider but tbh I found a small Snipe and Purple outfished it ! I am thinking maybe Griffiths Gnat or possibly just tying some tiny SHE in black, or maybe even small black buzzers ? Might add Dirty Duster as Wyatt swears by that too, it would possibly replace the Olive Paradun.
After speaking to John Walker I have been thinking about if I could fish the Don for a whole season with only two flies and what would they be. Here and now I would say Wyatt DHE and CDC and Elk. I reckon the DHE/SHE can be tied in various sizes and colours to represent March Browns, LDO's, Olives, Yellow May's etc and the CDC Elk (along with DHE) covers the important Sedge Period from June to Sept. I guess I am now a dry fly fisher at heart !
Lots of SBS's here
