This ended up being more verbose than I expected. Sorry for that in advance; I got carried away on my first post to LL. If you're in a hurry I think the Feisol tripod might be ok for you, but the Benro heads might not be strong enough for your large cameras.
I have the Feisol CT-3301 and Benro KS-1. I bought both direct, with no problems. The Feisol arrived with a broken leg angle lock lever, and they sent a 3-pack with replacement instructions immediately. Unlike some, I find the twist-locks easy to use and better than clamps. There is no good way to lock a head in place (just the one 3/8" screw at the top). I don't know if this is good or bad: sometimes the head comes loose, but of course it's just as easily tightened, and easy to remove for packing. The leg lengths/angles are easily adjusted but stay put.
The legs are not as stiff as I expected, coming from aluminum. Sometimes they remind me of PVC pipe, which is not really known as a photographic material. If a leg is fully extended it bends quite easily. I haven't gone to the local photo store and tried to bend their Gitzo's, maybe I'll do that this weekend if they're not looking. Usually if I have the tripod I have some other heavy stuff with me, and once I've suspended a bag full of lenses from the tripod it feels very, very solid. So there's that. The outer carbon layer on the legs is bidirectional weave, which surprised me, since I'm pretty sure the consensus is that bidirectional is more aesthetic than functional.
FYI do not buy the Feisol Arca-Swiss style QR plates. They are really thick, the rubber pad is squishy, and they don't fit in my Benro KS-1 QR holder. In contrast, the ones sold on Ebay by Qiqiwo are great. I like the Benro ones as well.
Now the KS-1 Benro head. I didn't have much option because I wanted a ball head, with Arca Swiss style QR, and I didn't want to spend a fortune on something that I would be getting wet, dropping on the ground, etc. The ball in my KS-1 is not asymmetric. I am not sure if it's supposed to be.. but of course this means if you have a heavy lens you'll get creep at steep angles. It definitely creeps a lot when using a 70-200/4, so now I use a tripod collar. If you have a heavy camera (Canon 1-series for example) and you want to precisely frame a picture with a longer lens, the creep might really bother you. It doesn't bother me too much because I have a small camera with only 95% viewfinder coverage, so I don't see what I'm getting anyways.
The KS-1 has a lot of knobs on it and I still get confused, but I'm getting better. All these knobs can get in the way when you drop into the slot for a vertical shot, but this is a shortcoming of many ballheads. Which is why L brackets look like a nice idea.
I mentioned this head comes loose on my Feisol. Usually the only time the head comes loose is when I am using the pan feature. The pan only supports one rotation, and I think it's less than 360 degrees. So when you are panning the head counterclockwise, you'll run up against the stop (which is a very unpleasant gritty feeling) and you'll start unscrewing the head. Classy. You can see why I rarely use the pan feature anymore.
All this may sound pretty bad, so you should know that I am somewhat of a perfectionist but also a notorious cheapskate, so I end up buying cheap things and then complaining about how they don't equal their expensive counterparts. If the Feisol cost as much as a Gitzo there is no way I would be happy with it. Likewise with the Benro ballhead, compared to an RRS head. The silver lining is that I can bash my gear against a rock or place it in checked luggage and not worry about it, and not make more insurance claims than necessary.
I read a review once of ballheads (possibly on this site) where the author said you should just buy the most expensive one you can find, because you will end up buying cheaper ones and upgrading to the best one sooner or later anyways. I think if you have $10k in cameras then $1k in support is not unreasonable.
