No contest - Koganinja hands down.First he has a great toss like the Top and he explains for beginners the dice sets , landing zone, XYZ axises ,and they are well produced.Like I said if you want people to engage your services show them what to expect Next would be Dice Coach- very personable, goes over the basics including betting strategies. Now Sharpshooter has nice videos but they are not on Utube.Someons gave me one and it had Jerry Patterson, Sharpshooter, and the " Sage" . Great OH toss vid. So at least you know what he can do. Sorry could not find anything on On Axis Forum videos.Scarce as hen's teeth . Now you will find videos from SRTs all over the place.Unfortunately little explanation usually comes with it. . So the EMMY goes to Koganinga !
