With the bases you have ordered i would make sure you use 12" tubes. The 12" will make it more user friendly when it comes time to laying out your post bases. A little more room for error. You can use a J bolt to anchor your bases but you need to make sure everything is in line. You do have some play with the slots in the base but not much. Or pour your tubes wait for them to set then snap a line from one end to the other and this will allow you to locate your post bases right on the money. Hammer drill your concrete and install wedge anchors(red devils). Which ever one you pick will be fine for what your doing. Have fun with your project.
