Pick the two hardest...

I've got 293, 294, 298, & 299 left for my MCSE:S. Since Transcender is having their 40% off sale, I think I'm going to try them, but I can only afford two at the moment. Of these four tests, which two tests would you buy?

Out of the four, I would say 299 and 293 was the toughest. If I remember correctly, the 293 was more like an extension to the Beast 291 (is it still called that?) and the 299 was all security. I found the 294 really easy as it was more Active Directory and 298 wasn't too bad as a lot of the questions can be answered without reading the scenarios and it had a lot of overlap from all of the other exams. I studied for both 299 and 298, but opted to take the 298 first as some suggested on TE and it wasn't bad at all.

So its a toss up of which one after 293.
On my way to MCSE 2K3: Security
My reasoning was that 293 came with 188 questions and 299 came with 214, whereas 294 & 298 only have 105 & 104. I'm not that worried about the exam format for 298, plus I'll have access to the Measureup practice exams if I need to get a feel for the format.
