A couple things. I may be wrong and hopefully Bruce will chime in if I am. As far as I know much of Bruce's Casting influence comes from James Chalmers, the Galeforce comp casting team, which includes Gerard Downey, and at one time Travis Johnson.
When I first asked Bruce for where to get advice about my Casting he told me, anything by Robert Gillespie and James Chalmers.
I know Robert Gillespie is very well respected if you read anything he writes, which is very educational, he talks about James Chalmers and his excellent form as a caster and also mentions how knowledgeable Al Buhr is on the subject, not to mention Toft and others. Also, I know he has a close relationship with Zack Williams. They cast together and discuss technique differences and even differ slightly in certain aspects of the Spey cast.
So I trust what he says because I think for the most part he is in the know when it comes to what the elite casters are doing.
As far as Zach Williams, I have been in contact with him on Speypages private messages throughout the years, when he was Casting at Speyorama with a 15' #10 fishing rod and kept track of his progress. Zach is obviously very gifted but I know he has put his time in on the water to go from obscurity to breaking into the finals at SOR with big boy casts that rival Travis Johnson Et Al. Also, he has zero tolerance for bullshixt so I trust him to only give only the facts. His demonstration at Poppy's Clave totally redirected me in my long line casting journey and now I know exactly what I need to do to advance in my long line casting.
Another thing I will ad to this discussion is that I remember a statement by Greg Bencivenga who was a finalist this year at SOR, at a time when he commented that he was casting further than ever with less energy than ever, and that has always stuck with me as he is known for his exquisite technique and knowledge.
The other thing I will ad in reply to Vics statement about casting over the anchor is that it seems to be very evident in Brian Styskals Speycraft project video. I have watched this thing for the past 7 years without seeing that. When I finally started to put this into practice and got the revelation for myself I thought, Gee, I wonder how many spey lines have been chopped and whittled in the name of better turnover if I and others had known and understood this technique.
The question I have is this: After watching quite a few forward casting strokes by the best castors in the world including those mentioned above, and including Tellis, Tommy Aarkvisla, Sakke, and others including Speyorama finalists I see where the majority of the bottom hand movement in the forward cast seems to come during the translation part of the cast where both hands are traveling down powerfully together as seen in Bruce's Snakeroll, but there are a few that do pull up more towards the armpit or upper top arm at the end of the cast as Vic is promoting and it works best for me. I seem to have a better cast myself when I use this technique but my initial thought is that it gives me a longer casting stroke. Tellis seems to do this also, so obviously he is copying me.
The other thing I will mention is that I was talking with Gene Oswald, another top ten SOR mens finalist and he mentioned that some of the casters like Tim Arsenault manufactured tremendous line speed and narrow, pointy loops While others like Johnson had a little more of a Tank Track shape. The tank track guys seem to eek out the pointy loop guys at SOR. It was an open ended discussion and Gene is such a gentleman that he presented it as food for thought and we did not have the time to go deep so I didn't query. So I would like to hear thoughts on bottom hand use, rotation, loop shape.
The last question I have is in regards to drift. High is good. How about drifting back before the forward cast? Inevitable? Necessary? a little is ok? or possibly done wrong it can lead to trouble?
