Well, my LHS did not have the 13x4W. I went ahead and bought a 13x8, had my hobby shop order a 13x4 and it should be in by Wed. I am going to try out the 13x8, it is not the Wide, but I will see what it can do. If it works or not I am going to throw the 13x4 on, see if it gives me more performance. Thanks for the info, I will be taking my digital camera down so I can hopefully post some photos later tommorow.
