I'm looking at a couple of tradeoffs. My school won't have the official courseware for v7 untill July, so if I went that route I'd have to juggle some other certs around and take them first. Also I'm noticing there aren't any published study guides for v7 out yet. That's a bigger problem in my mind because the official courseware looks more like reference material than something I'd use for actual study.
But I've heard the v7 is much better than v6, and I'm certainly interested in learning the latest and greatest attacks, not to mention the frankenstein toolkit sounds pretty cool. So what I'm trying to find out is whether v7 is really that different than v6, or whether I can take v6 and easily pick up anything missing on my own.
