Yeh, I get the idea fo adding a little redundancy and buffer with the new found "free weight". But...
Personally, I'd reserve a few ounces of that for a strictly "reward" item for the weight loss effort. Something like a Tenkara fishing rig, or a Kindle, or yes, even a *gasp* chair!
I think it's important for any kind of loss/quit program to have some kind of non-essential reward involved, even if it ends up being just temporary.
