Last six months, I have been working on long distance casting with single, double and snake roll. I use 8/9 or 9/10 midspey line with 15' footer- 10/11 old GLX, T&T1015-3 or Sage 9150-4. I was able to cast 130 to 140' including leader - not consistently though, with underlining the rod, better handling of running line off the water, using the bottom hand more- tighter loop, longer and higher forward stroke. I believe I can not cast 140' consistently because I can not cast 150'. When I cast 110'+, bending more butt section, starting forward stroke at 2 or even 21/2 o' clock, my loop gets wider about 4' more. Do you think that wider loop keeps me from longer distance casting? or something else is missing here? I appreciate any thoughts or opinions.
