Getting lots of tips and re-enforcement from the video clips, yours and others included, great. Being self taught does not help, all those bad muscle memory casting groups have to be relearned , which isn't to bad as we are always evolving and it freshens us up. My main fault stems from tight quarters fishing, back up against vegetation or structure, my setup and cast is out in front, arms often out stretched to create d-loop space behind.
But, all is not lost as this forum and you guys are a source of relevant casting instruction, thanks, keep it coming.
My fish catching casts are in the 40-70' range at the most, so the other day after watching some of your videos I went down to the river armed with my VSL 6/7, 420gr rage compact, 14' fast sink poly and kept concentration on that bottom hand and a tight forehand elbow, some torso rotation, WOW , not every cast as I am human after all , but a big improvement if I look back 7 years ago when I first cast an A3 6wt switch with a scandi head.
Think there was less than 6 turns of grip shooter on the reel with some the better casts
Looking forward to shooting some line soon on the Birth Place of Spey.
