You got your money's worth out of the bars! I have found, when putting boats on the Element, that using J-racks is a bit easier for me. Not quite as far a reach to get to the cross bar straps in the middle of the roof. The downside is they are 14" higher than the roof...so I take them off when I am not using them.
I paddled Lake Singletary and the Holden Reservior out in your area a few years ago. The reservoir was a pleasant paddle...Singletary was pretty busy!
Again...your set up looks good!
