Yeah I'd love to get some impressions of the RRS and Kirk options so I know what to get.

I don't know what you are currently using, but I'm not sure the camera matters much
What I did notice is that I had to tighten it, wobble it, tighten again, and repeat 2-3 times to get it to the point where I could not detect any play. I did not like that. I don't want a lens foot that allows for any play in the lens. I may keep it tight and never remove it if it ever becomes a issue.
By choosing a generic product, please don't expect new advancements in DSLR technology by Canon, or for new lenses to come out. R&D budgets come out of sales dollars.
I do think the fact that they are clearly knocking off these lenses is a knock on their reputation.
As I keep telling people, the old one was very good optically, but only under ideal conditions (IS off or stopped down a stop). The new one seems to be massively better under regular high stress conditions (wide oopen with the IS in, and in resisting flare and CA.
I think apart from a rotating zoom (to which people seem to have mixed feelings) the usability with the TCs as confirmed by the MTFs, a reliable and more powerful IS, along with the much improved IQ is a sufficiently good reason for the widespread welcome this lens is getting.
