You'll be happy

>Seeing a friend's 290 in action is what prompted me to buy a slightly bigger one. That 290 was impressive and would be a great choice for most woodturners.
Regarding the bar(s) - nobody will regret having a longer bar as they do come in handy, but you're better sizing the bar to the task. The saw will handle better and be safer, too. You can always cut smaller stuff with a larger bar, but not the other way, so if its only one bar you're looking at, for me, I'd choose the 20". You can, and probably will, choose to buy smaller bars down the road.
Now about that chain - rip chain and standard chain have little in common, and rip chain isn't something to be toyed with. Keep the grind on your chain that it comes with - you can do plenty of ripping with that standard 3/8" chain your Stihl will come with. No need at all to go changing things around. That can get dangerous, too. I find having 2 chains for each bar is very handy. One more thing about the chain - be prepared to sharpen it often - the first time you hit a rock, or even earth, you'll dull it to the point of near uselessness.
Enjoy that saw - it'll be hard not to.
CharlieVA - thats the saw you recently picked up, right?
