It appears to me that RRS's business model is to lock customers into buying RRS components and to shut them out from buying competitors' products. This may be good for RRS but it's bad for consumers. I was looking at the RRS site this weekend and now see that you can only use RRS clamps on their ballheads. This can be a risky model as it's the antithesis of what MCAsan is talking about in post #8 above. I certainly don't like it, and while I think that RRS clamps and plates are of the highest construction quality I think in some cases they are poorly designed. I wouldn't buy a ballhead or tripod from them either as I think they've yet to prove themselves.
OTOH Markins have taken the opposite tack; they try to work with everything out there. Their lever clamp has adjustment mechanics that allows you to use various plates, they will fit an RRS clamp to one of their ballheads if you send it to them. I'm sure that kind of attitude has won them sales and their construction quality is on a par with that of RRS. I've been using a Markins clamp on a Linhof ballhead for years with plates from four or five different companies and I've never had a problem. It's a no-brainer and as I said above I'm prepared to pay for custom machining so it will bolt onto an A-S Z1 stem. I'm hopeful that RRS will rethink their strategy but I'm not holding my breath...
I've no idea what you've got against RRS but in every ball head post you interject how great Markins is and what a PITA RRS is. Anyway you are utterly wrong about RRS' compatibility.
RRS does have a disclaimer that their lever clamp should only use RRS or Wimberley plates, but this disclaimer is only for the the lever release clamps. Like Jon said, RRS offers both a screw type clamp and an option for no clamp. They are not discriminating against any system, nor are they forcing you to use theirs. If you want an RRS lever release clamp then you should use RRS or Wimberley plates. If you want to use something else, then get the screw type or another manufacturer's clamp, they even offer 1/4-20 or M6 threading.
I have used Markins, Bogen, Giottos, Acratech, and RRS. I still use RRS and Acratech ball heads, I have a smattering of RRS, Acratech, Kirk, generic plates, so far all of them seem to have an adequate connection with my RRS lever clamp. RRS is probably, no definitely, the finest ball head I've used. Acratech is the lightest head I've used that still has adequate clamping ability.
RRS has been around for a long time. They've been at this stuff since 1990, that's 20 years in the business. The BH-55 has been around since 2004. I trust their products, there are very few that don't praise the products that are produced by RRS. They also stand behind their stuff. Since Joe Johnson took the company over they not only produce top quality equipment, but they are easy to do business with too.
Finally, the Markins QR lever release is nice, and, yes, it will work with many types of plates (so will the RRS, I have proven this to myself with my equipment, I think there may have been some problems with some plates, maybe even runs of plates, thus the disclaimer). But in order to work with the wide variety of plates the clamp must be adjusted, and IMO this defeats the original intent of the lever release.
