I use castle in the winter just because we are off matts and I actually use the orange one which I think is the highest one but I do hover driver at address. Other than that I just use normal tee's I think some have marking on but don't really ever reference it that way,
I have a guy I play with who is semi retired, You can tell when you find one of his balls or tee's as he has coloured them a particular way. I was like you have way to much time on your hands
... I also had a peak into his score card holder and he has notes basically saying "Focus on the next shot/hole" etc etc I kind of respected it, everyone else ripped him for it
