Let me start by saying I do not have a huge budget (hopefully far under $500), and I do not use a tripod so often that I need the best. I have not used my tripod in a few months and I know that a new setup will give me the kick in the pants I need to get back out there 
I have a 055proB with 498rc2 head. The heaviest I will be shooting with is a gripped 5DIII and a 70-200 II with a 2x extender. I should mention that a lot of my shooting with a tripod will be near the ocean or a lake and the legs will get wet with seawater. My current legs have been covered in sand many times.
I mainly want to get into an Arca Swiss style head. I am wanting to upgrade the head to a Surui k40x. I know the 30 is often suggested but I am not afraid of some extra weight and I prefer overkill for only a few bucks more.
After reading around, I am somewhat set on the head but am also looking at new legs at the same time (only because my son uses the tripod also and it would be nice to have 2 setups - I feel the 055prob is decent enough for my needs.) Is there a combo that I should take a look at? Would you get the Surui head and put it on the Manfrotto legs?
If I do get the Surui K40, I would feel comfortable spending maybe 300 on legs. That would keep me under $500. I wouldnt want to spend the whole $500 on a head and put it on the manfrotto tripod. That'd be like building a mansion in the ghetto. 
Any suggestions are appreciated. Thank you for reading.
