I have the 72mm and can categorically say that you DO need the CF for Chromes.
Don't kid yourself that you can correct this in LR/PS; the drop-off is too significant. The corners are just too dark if you're exposing for the centre.

Ok, don't laugh at my crappy imagery and issues with light leaks and static, lol.
For sharing and learning purposes only... The 3 images I took that day with the 150 XL, same filter, relatively the same settings f/22-f/45 and around 1/125th or so etc, I suspect that more contrast filled bright light scene will accentuate the issue, even the close up image seems to have it a bit, though not quite as bad. That last shot of the sand I was experimenting, so sorry it's so crappy. Hope this helps the OP. Also, I thought I worked on the vignette more, but now looking at it I must not have, I think I did, didn't like how the center lost some of its "pop" and "undid" it.
Come on guys this is not the discussion portion of the forum.
If you want to help the guy can't you PM him? We use to do this all the time.
The Super Symmar XL series has more light falloff than the Biogon-derived wide angle designs such as the Nikon SW, Super Angulons, Grandagons, etc. See Michael Brigg's post in the following thread:

Having said all that, I would agree that if you use extensive movements you will typically want to use the SA72XL center filter with chrome film. Neg film might be more of a toss-up depending on how much edge vignetting you find aesthetically acceptable.
