Hi Tony; sounds like you have a similar outlook to your fishing as me although I do occasionally like to catch a few Carp on my local estate lake.
I belong to Verulum AC which also has fishing at Fishers Green on their book although I’ve still yet to fish there. I also used to fish at Kings Weir; which you mentioned; but haven’t fished there since the new concrete weir was installed.
Me holding a nice Chub at the old Kings weir taken in the middle to late 1980s before the new concrete weir was installed.
I used to belong to Welwyn Garden City AC which had a couple of stretches of the Lea; at the WGC park and a stretch about a mile or two downstream of Hertford at Bayfordbury.
I now belong to Verulum AC which has several stretches of the river Lea on their books including the Fishers Green stretches and many others including the river/stream like section in my avatar; plus several other rivers and stillwaters in the Herts and Beds areas.
Like yourself (according to your other post regarding the Speedia) I also enjoy trotting in certain stretches of river using a centrepin; and I also like to touch leger (using a fixed spool reel); and am usually fishing for Barbel & Chub and occasionally for decent sized Roach and Dace.
Anyway it’s nice to see yet another running water Angler and Pin user on FM; there are now quite a few of us
