Too Much of a New Thing?

I'm starting this new hat.  It's going to look awesome!  It's an entrelac hat, a knitting skill I've never undertaken.  I'm working with a new yarn that I've never used before, compliments of my swap partner.  It also required a new cast on, which I thought would look wonderful!  It's a tubular cast on that requires you to pick up the stitches from your cast on and continue on with the project.  It sounded wonderful and looked even better!

Unfortunately, after I attempted to cast on, I found that the yarn was, well, not co-operating.  Knitting into that first row was like torture, though the rows after that weren't too bad.  Then trying to pick up those stitches, that was a nightmare!  I was beginning to wonder what I did wrong!  Now I think I'm just going to go back and knit it the way I typically start a hat, doing the ribbing in two needle sizes smaller and go from there with a regular cast on.  I might be adventurous enough to try that new cast on again, should I decide to start all over, but for now, I think I'll be happy just to try one new skill and one new yarn at the same time!
