Per the title of my new post, has anyone checked them out or seen them? From what I can tell, of all the info I've read on them so far, they appear to be identical to the prior version, except that the internal area of the clamping mechanism is supposedly "new and improved." The "B" version is being promoted as the new 2014 model. The prior version is of course the 2013 model. Price difference is about $30 between the two, with the newest version being the more spendy. Worth the extra $30 to have the latest-n-greatest thing in this case?
