extension tubes - before or after lens adapter ?

I will be using an EF 100mm Macro lens on an R6.   I want to buy extension tubes for this combo.  Does it matter if I put RF tubes on the camera or EF tubes on the lens?  The EF tubes are a bit less expensive.

RF 24-70 lens zoom ring is not smooth

Bought this lens from B&H in late May.  Now > 30 days since purchase.  Shot a bunch of video with it this week, zooming in and out of the subject action (sport).  It's not smooth.  What would you do about that?   I haven't called B&H yet.

Resolved! What lens do I need?

Hi, I recently purchased a EOS R RF 24-105mm F4-7.1 IS STM KIT.  My other camera was pretty old and I didn't pay attention to the zoom potential.  With my old camera, it had an optical 50x zoom and I could get very close with small things far away.  ...
