Playability is good. I find it as easy to play as my Les Paul. It's better to play rhythm on than lead. Mainly because the frets are big and high and the neck is chunky - and that's how I wanted it. My hands don't get tired playing barre chords anymore. Lead isn't a problem though; just not as easy as rhythm.
The Bigsby is pretty cool. Not really a whammy, I use it for gentle trem effects, usually at the end or during a pause while soloing. It's really good for playing chords too. I find it a lot more effective than the Strat trem.
Yes, if I fiddle around too much, it does go out of tune. Only Floyd Roses consistently stay in tune. But I've notched the nut and bridge really smooth, so I only need to recheck tuning every 10-15 minutes when jamming. When playing alone it doesnt bother me.
Yeah, I know, I left the chakra out but it would've looked silly, half cut out. Was planning to put it on the headstock, but put my name there instead!
I'm working on a little site on my guitar, and will post a link here once I'm through with that.
