I have noticed that UK ‘buzzers’ are often tied ever so more slender than Canadian ‘chironomids’ and U.S. ‘midges’. I like the slender ties, but confess I often fatten up many of my flies.  This is partly because I start with too large a hook for the actual insect and then add too many materials. Also, because I am an ‘impressionistic’ tier I like the flare and movement of exaggerated thoraxes/wings. It is good to note the more slender creations.  

I have noted before that a friend of mine is an avid ‘gnat’ fisherman on impoundments in the NW and his creations are slender, delicate creations (sizes 10-18) that generate lots of attention.
