I'm a traditionalist


...especially when it comes to blobs or blob boobies !
For Pulling
The hook (single) should be a Drennen Trad Wet Size 8...strong with an excellent/perfect gape...and yes you can still get a very close copy alternative that is equally as good !
Or in a double a Kamazan B175 size 10 (with the eye bent down to fit the international rules gauge)....Partridge "Big Mouth Nymph Doubles" would be my 2nd choice for a double...(but avoid the Partridge "Big Mouth Double".....the gape is too wide,,and you'll bounce a lot of fish) - Partridge have 2 different double hooks in the "big mouth" series
Tail if used...UV Flashabou, Pearl Crinkle Flash or Marabou
As for the Fritz......the diameter of the material plays a big part in the colour of the fritz, as light passes through it and how the dye takes to the material etc........also how the material sits on the hook...you want it bulky but not too bulky or it will cover the point/gape of the hook and so comprimise hooking.
I only ever use transclucent fritz...i think it gives more vibrant colours...(i hate the UV or Boosted stuff..i think it's too much most of the time and puts fish off ! )
I also only ever use 15mm Fritz.....for standard blobs and boobies......and straggle etc...for nymph thorax's and patterns to be fished slower...
A good quality fritz, with good strong vibrant colour is vitally important in my opinion...especially when it comes to blobs...
