EDIT 6/03: Idk if you're still interested, but I have used the ones I bought to carry a bike and about 100 lbs of luggage for a 900 mile trip and they held up. No wind noise, no caps popped off, no trouble at all. I am very satisfied with these.

I just installed ones I bought off Amazon today for my 2009 EX. So far, the installation was very straightforward and easy. No problems with the size or anything feeling loose. The quality looks good, overall. I need these for roadtrips so I'm hoping there are no issues travelling 70+ for 300 miles straight. I'll be trying them out a bit and then I'll come back with a review.

Here are the ones I bought if you're curious: https://www.amazon.com/dp/B0045V8CKU?ref=ppx_pop_mob_ap_share
