regarding the capis... unless you are trending outside the normal path somehow (ie you've been called for an interview, have gotten unusal requests for further information (not just the standard "original documents request", but actual specific requests that aren't standard from kgn), have a ARC (authorization for return to canada), or your timelines are outside the average (15m-ish i think?)... i believe the general consensus is that CAPIS notes are pretty much useless (i.e. blank)... i'd say it's not worth while to try, but i understand the feeling of helplessness when it's doing SOMETHING rather than nothing but waiting...
from what i remember, a few people who no longer keep up with the boards regularily have ordered CAPIS for their applications out of kgn... i seem to recall they were in the categories above and wanted to find out reasons for interviews or extensive delays... they can be useful when you know what you are looking for and know it's in there, but probably frustrating at best when there's nothing really to see....
good luck...
