Thought I would make a comment on Vintage Golfer. To understand his view point and his YT channel one needs to look at more of his content. Majority of drivers he has videos on are wood and mostly persimmon. These are various steel shafts and deep bore insertion. He has very little knowledge of minor brands and like most think minor brands are inferior.
I posted the SMT 455DB/VS339 as I thought some of you would like it and Mike would get a kick out of it. Vintage Golfer is more like the average golfer than a great scratch player so his experience is more like the majority playing golf.
I do like Vintage Golfer's YT channel as I play a lot of classic clubs myself.
