So far, so good...just remember: the Intellijel tile format requires an odd sort of spacing between the row's rails. Using the endplates from Synthrotek, etc will give you the 'normal' spacing; I would suggest getting one of the longer Intellijel tiles (like the QuadrATT) first and using it as a template for that row to make sure you've got it nailed. I'm assuming that the tile row will be at an intermediate angle between those used for the upper and lower rows?
