Just reading out of curiosity and I'm surprised to see so may wood tee responses.

My course has standard, long and short plastic white tees and has had them for years. They are better than any tees I've ever had to buy and I grab a handful here and there and I use them everywhere. The wood ones leave a mark on my driver, they break often and I don't like that.

I just searched online though and I think I found the tees... Champ Zarma Flytee

I also use Plastic tees. A short one for the par 3's and a longer one for my driver. I probably use the same one for at least 10-15 rounds. They don't break, maybe just bend slightly.

I use mostly plastic but am not fussy...whatever I find works for me. I haven't had to buy tees in years!

Wooden castle tees , delivered in brown envelops so no plastic

I have been using the red tee's and white tee's from Vice Golf. They are really good and also match the Titleist branding well.

I have recently purchased some bamboo tee's, they look pretty, will let you know how I get on!!

Use black wooden for the driver, as I don’t like the marks white wooden tees leave
Got some small red plastic castle tees ‍♂️ For par 3’s
Off course the red and black go with the team titleist theme colours

I like to use tees from the kingsley club because they are made of bamboo and you are able to get alot of uses out of them.
