Thanks for the replay. Your pics helped a lot. I think I will go with the 44" as it seems like it fills the roof better.I have the 43" aero load bars and the 44" fairing, although I haven't used the fairing for a while. It does cut the wind noise quite a bit, but I think it looks kinda ugly IMO. Especially on the hatch, it looks off balance. I only have the roof rack on when I'm loading my SUP, otherwise I remove it and keep it in the back. If you have full length pads on the bars like I do for my wide board, then they don't make as much wind noise as without. Here's some old pics for my bike set up, sorry no head-on pic.
