I would really, really, recommend you don't do very long time spreads on the SPX. Last Nov when the vix was lower than it is today I did a put calendar (Nov/Mar)and it hasn't paid. Perhaps just bad timing on my part. I won't do it again.
The folks doing diagonals do them only one month out with very good reason...simply those are the best odds. I think the far out month (3-4 months) puts/calls on the SPX are just flat out overpriced. Remember time=synthetic volatility thus farther out in time you go the higher the vol's and the higher the price you have to pay. Tred lightly.

I'm looking at opening an Apr/May put diagonal but not until very close to March exp or just after. My diagonal would have made money had I not tried to leg into it...
