FM member burningheart had a very good IR lens test page listed for selected lenses on FM a few years ago which was very reliable and fitted often with my experience, too.
Yes, having a FF body converted will make the photo bag heavier! Ok, now there are other options out there which reduce the camera weight with a FF mirrorless camera (for example as regular color-based camera in addition to a converted FF DSLR body) but this is a different topic....
I remember that list, but it's only about hotspots and tells nothing about (corner) sharpness ;-(
Most of my primes are not on this list so I can't really comment.
I would be interested in a mirrorless FF body for IR, because I like having an EVF for IR (instead of just Liveview). Let's see if something interesting comes up at Photokina from Canon or Sony ;-)

No personal experience, but I have seen several people using this lens for IR on FF, so it's probably a good choice (just like the 17-40). For the 17-40 I wonder though how good the corners are at the WA end of the range in IR, given that other Canon zooms like the 10-22 and 15-85 have obvious problems there.
Here is a good example from my 17-40/4 L lens performing in infrared (uncropped photos).
First, 17 mm at f/7.1

Looks good but corner quality is difficult to judge at this size. With my 15-85IS at 15-24mm or so, from about 2 MP picture size corner quality is starting to become a problem, at least for subjects where one would expect fine detail in the corners. For some examples check originals in this album:
Both look very good , but I have to say they are 2 of the least IR looking images I've seen (maybe that's why I like them )
How much different to a well processed NORMAL B&W would those be ?

Thanks, Ian - the great thing in IR photography is that it allows a huge range of post processing. False color, traditional IR look, B&W look, abstracts. The photo below is taken in color and B&W processed - you can tell the difference especially when looking at the bright white algae on the rocks in the IR shot. It's all fun

Beautiful photos in your link, too! I especially looked closely at the ones taken at 15 mm FL, but I didn't see severe issues in regard to corner sharpness. Maybe this is more visible when zoomed in at large.
When stopped down, the 17-40/4 is a great performer IMO also in regard to corner sharpness. My TSE lenses are a step up in the corner sharpness still, but I am absolutely fine with the performance of this zoom lens.
