.8 or 1.0 Bar Wastegate Spring - Which to Install?

Well, I bought a 1 bar spring last month and an .8 bar spring off of Ebay that arrived today.
The moment of truth is here: which one to install. Currently there is a 1.2 bar spring installed by the PO I've never felt comfortable with it and really haven't driven my car very hard as a result.
Over on Rennlist there's a guy running a 1 bar spring with a stock WUR and fuel head. His posted dyno runs show a 11/1 AFR at WOT.
Still, I'm looking for opinions.
