Hi Steve,

I, too, am here in northern MN, about 100 miles due west of you between 
Grand Rapids and Bemidji (closer to GR).  I have grown hundreds of 
rebloomers over the last decade, but only six have ever actually 
rebloomed for me.  Of those, only three are TBs, and of those three, 
only one has rebloomed twice in the last decade (different years):

Champagne Elegance TB - rebloomed once about a month after spring 
bloom, then promptly died.

Sugar Blues TB - rebloomed once

Lilting TB - rebloomed twice (different years) but is a very slow 
increaser

Low Ho Silver IB - rebloomed once

Faux Pas IB - rebloomed once then promptly died

What Again SDB - rebloomed once

Queen Dorothy TB - almost rebloomed once but got caught by frost just 
before the first bud opened

I don't know how helpful, if any, that information will be to you.  At 
least it confirms that rebloom is possible in our climate.
