Wescott Scrim Jim or Lastolite Skylite?

I'm looking for a 48x72" framed diffuser kit for outdoor location work. I have already done a search on the subject and read the threads on here. There is not much difference in price and the customers rate them very similiar fron BH Photo Video's website. Do you have some experience or opinions on either of these or comparisons? I'm sure if I saw both in person then it would be easier to make a decision but this won't be the case, unfortunately.

Chimera based on what I heard from various folks here and POTN.
