Arc Launcher question

I have loaded the go launcher onto my Arc. I like this launcher a lot & would like to keep it as the primary launcher, but I want to be able to get back to the tapestries launcher too. I have not set the home screen to default to the Go luancher as I'm worried I won't be able to get back to the tapestries one again. But it's getting annoying having to pick the launcher every time I hit home.

Is there a way to go back to tapestries once I set the Go launcher as the default? I thought I could choose the "exit go Launcher" option but that doesn't take me back to the other screen.

Any help with this would be appreciated.
