not too familiar with Track tactics events, but if future events are going to be run like their event(s) from last year, i'll probably do one with them. if they don't have a structured class room for novice, definitely go with midohio PTR, motoseries, or STT for your first (or first few) track days. if you're already an accomplished rider (good body position, smooth on gas, brakes, good lines, know where to look, etc etc etc) then you might not need a class... but i would generally recommend a good well thought out class session for at least your first track day.
