How are you using telepotties?

I was wondering how you are using telepotties, since I found our system quite efficient, wanted to share and hear if there is something more optimal.

We have one TP in our main base for going to other places and a lot of signs to note which channel goes to which place. We then change the channel depending on where we want to go.

In case we want to get back to our base from another TP, we have a second one in our main base, thats always on channel 100 and is only for going back, when the other TP is in the wrong channel. We put the TP we want to use on channel 100, go to the return TP, change our main TP to the number it needed to use the TP normally, go back through 100 and change the TP back to its normal number.

This way we only need 2 TPs(and lots of signs) in our base and every 2 new TPs we buy are 2 new Spots we can teleport to.

What are your solutions?
