cypress tree has branches bent during ice storm

OK, posted this on the OT, but surprise, I didn't get any reasonable advice. I got a pics or it didn't happen, and am currently waiting for someone to suggest to piihb.

Anyways, I have a couple of young cypress trees. The ice storm obviously bent them over quite a bit, but the have for the most part recovered.

Some of the branches on the sides are still bent, some as far as 90 degrees. Now, should I just tie them to the trunk with some arbor tie and hope they straighten out? If they don't within a year, do you prune them?

What say the outdoor board on this issue? Cant get any worse advice than from the OT...
