Okay, first off here's the reconfigured Ommagang:
So my current on the fly experiment is based on the cuffs for this - the mountain view cardigan: http://www.ravelry.com/patterns/library/mountain-view-cardigan. Mines going to be a pullover with a deep u shaped neck. I'm using Parragon http://www.knitpicks.com/yarns/Paragon_Sport_Yarn__D5420300.html in navy and I really like it. It's got a nice tight twist and a lovely hand. Right now that project looks like a thnead so I'll snap a pic when it looks more like a sweater.
