Since I'm a big fan of bluegrass music (though I've never been in a band, just a duo), I always assumed I'd stick with an f-hole mandolin. But a couple of weeks ago I found myself in a sweet little music store (http://www.acoustic-corner.com/) in Black Mountain, NC, and fell in love with an oval-hole A-style. So--am I fickle, or just confused? BTW I didn't buy it, as it's not in the budget right now, but I seem to have changed my tune a bit.
rev buy an oval hole. they make a good stable mate for the f hole. plus u can't have to many mandolins.
