Morlie;

Much as I hate to admit,  I tend to agree with AA-man on this.

How to get  mineral wool batts through a tiny 2' access ?

There's nothing nice or easy about a retro-fit insulation job for any  
crawlspace no matter what the insulation choice but getting flexible batts  
through a nominal 2'x2'  access shouldn't be a challenge for the poor  
schmoes who get the task .

As for the "guy" that told you 2" of closed cell foam would be "enough for  
Canada", you can tell him that I, a Canadian, in Canada,  said he's full  
of $#!+ and if I were there, I'd boot him in the arse and tell him to get  
lost, chase him off of the property and be giving him an expletive-laden  
outline of his family tree while doing so.

If one were foolish enough to provide only R-12 under a suspended floor in  
Canada, that fool would be guaranteed to have frozen and burst plumbing,  
cold floors, etc.
