MCKCONRR posted:There are pro's and con's to every system so just get what appeals to you. My only stay away would be MTH because the spring pins are such garbage. I have junked so much of it when buying collections. Someone mentioned that fast tracks pins will sometimes break. They can but it seems to only happen with repeated connecting and disconnecting of aging track. You can replace the pins though. You can bend the tabs and pop the rail up, replace the pin, lay the rail back down, and bend back the pins. Someone else mentioned you can't make custom piece which is also not correct. I have been making them for different seasonal layouts since the system was introduced.
It's certainly possible, it's just a bit more work to it than cutting a piece of tubular and replacing the pins.
