FMS is not that big of a deal. If you know enough about computers to post at this site, you can figure out an FMS without a special class. If getting on at 850 hours vs 1000 hours means that much to ya, then go for it.
He's right. Don't stress too much about "FMS" expereince. It's not that big a deal. It's not worth the money. Plus most are pretty different any way.
