Thank you; this is indeed faster; I've replaced my definition with yours. However, I was hoping for a solution that would complete in about half the time of the solutions I provided. That is, I'd like a 2x or 100% speedup; drag is only about 20% faster than drag0 on my dataset.

Any other lines of attack?
