Curved Log Cabin settings?

I finally finished piecing all the blocks for my curved log cabin quilt. Now I have to decide how to set the blocks. This will be a bigger quilt than I usually make and turns out I don't have a design wall big enough to try layout possibilities. I tried 2 different layouts on my living room floor but really need to try a couple more before making a decision.

Which layout do you like better? I think I like the 2nd one. (click photos for larger view)
