Is it possible to have more than 1 home replacement, and switch between them using the Home Chooser?
Yep, that's why there are home switchers... problem is you can eat up a TON of memory that way. Or they will lag like crazy on the first load as you switch (if they are closed or cleared from the memory). But to do it temporarily to figure out which one you want, yes, you can.
You are right to be wary. There is much bullcrap. Be wary of me too, because I may be wrong. Make up your own mind after you evaluate all the evidence and the logic. - Mark Rippetoe
