Dave -
I played for decades before joining up and stepped into the Intermediate course with a determination to fix a lot of bad habits I’d developed over the years. There was a lot I already thought I knew but I went through it anyway and pretty consistently found tidbits to help straighten out my faults. I also found myself dipping selectively back into the beginner course (ego be damned!) to iron out things I’d been too pig-headed over the years to fix.
Nice thing about GT is that you can bounce around. Go ahead any try the intermediate. If it swings -awesome! If not, drop back to the basic. Nobody is watching and if the are, tell them to get stuffed. Jump in. Have fun.
