Replying to Look PX 12 Jib bindings?

So I went on Look's site and I saw that they only have a 90mm version of the Jibs, but I need a 100mm brake, so I went on google and found these: http://shop.aspeneast.com/browse.cfm/look-px12-jib-binding-with-100mm-brake/4,3485.html I know it says 2010/2011 but can some one tell me actually what year these are from, and if they are good? That would be great! And also, they used to have the jibs in like 90, 100, and 120mm, but now they only have them in 90 mm right?
