It's all relative. What works for some, doesn't work for others... ie, cpu overclock settings differ between phones. We have all seen examples of this. I have personally flashed and used Optimus V recoveries and ROMs. Particularly when aospCMod was the only gingerbread port available for the Optimus, I ran it on my Optimus S. So, sometimes it works, sometimes it doesn't.
I guess you can consider me a guinea pig! I'm still fearful of the dreaded brick!
It's just not recommended that everyone try this as undesired results to come from doing things like this... As stated in my post above, I don't mind being a guinea pig too, there's always a way to get back to working condition but not everyone knows that.
