*lesigh* FX does a great job pioneering clever new technology, which we all appreciate, however I do genuinely wish they'd take a little more time to stabilize their designs before putting them out on the market. As annoying as it is for us, it must be an absolute nightmare internally dealing with all the different parts and specs for all the different revs. FX, as much as I love them, are definitely a company you DON'T want to buy the latest and greatest product from because the design is inevitably going to be tweaked. I give them credit though, when they see a problem (some of which you only learn about in production) they do go and make the changes, and quickly, as well as continuing to support old revs. It probably isn't lost on them what a nightmare that is to do.
