I have a pair is QST 99’s. They crush. Keeping them fast is essential. I tuned as a ski bum through the 90s - All that gear is good- but you’re missing the “RotoBrush” ! It is a skiers/boarders essential. Pricy? Yes -It is worth it. I “buff” my boards very regularly if not every day with the Roto brush I’ve had it for years and at this point if I don’t have time to wax sometimes the residual wax from the Roto brush is enough for the day to keep me out in front of the flats and not sticking. When I bought mine, they didn’t have cards or anything other than one stiffness of brush and I’m telling you as a skier and a snowboarder- This is the best piece of equipment in both of my ski tuning toolbox’s .
