peja, there are alot of players who notch/know distances but simple shots like 4s FP and 5s lg, low winds, and that's it.
Almost every shot that is a direct hit is notchable, LG zooks, floorbanks, trapshots, transfers, banks(roughly), this is the only difference between barman and the rest, at least barman bothered to learn the cool shots.
As I have said before, I learned how to notch 4s nades from m3ntal when I 1st met him, I learned everything else myself without any visual aids whatsoever, all my notches were just roughly guessed by which I mean I never actually knew exactly what pixel a grenade would bounce, apparently, barman did, no one can notch the trick shots I used to do, only person i've seen at my level for trick shots is lacoste, but ever since I left b2b, I stopped playing trick BnG's, to be quite honest that's the worst experience for me ever on WA, I really miss b2b's Thursday night Tournaments n stuff...
1st Tournament I entered I missed 3 shots the entire Tournament, I remember beating franz in 5 shots and he couldn't believe it, shortly after KRD convinced me notching was lame, I stopped notching in BnGs ever since, I started notching again last year against other notchers and players who play "lame" but I still to this day mirror my opponents fairness in BnG, I discuss notching with barman during BnG's, but not because we do it, just because we understand each others intentions in this way...
My only concern with notching, is not everyone wants to learn it, if everyone wanted to learn it, I would be totally fine with it, I would encourage it, and go out my way to provide an easy to read tuturial, but it's a ridiculous advantage over anyone who plays fair and instinctual, especially at the level myself/barman/mablak/darKz/anubis could do it, no one has a chance to beat us, it's just really really unfair...
