Trust me, I throw putts high on other baskets too. They just don't make that deflating metal "thunk" sound.
The 3-dimension putting description is dead on.
I was thinking about how cool the Lake Stevens baskets are, and how if you could set up the basket so it could be simply rotated on occasion you could change the way the hole plays without needing additional sleeves. Even better if they could show the direction of the basket when applicable, on the tee sign.
Yeah, I think that's always a good option - letting the people know where they're throwing. It's like putting a sign at the tee telling what the pin position is today, only telling them where the "guard chains" are instead. But it would be helpful to have signs to start with. (Now some guy out there is going to hand me a toolbag and set me to work on it).
One of the coolest things out there (speaking of tee signs) is at Tyler State Park. They have a little dial on each tee sign that you can rotate, and it says A, B, or C depending on the current pin position.
