Interesting list. Thanks for doing it!
I think the top part of this list is certainly pretty clear - the only team I haven't heard much about is SMUS, though they're usually pretty strong.
A bit surprised by how high Fleetwood is - they had a big win vs. Tamanawis, but had lost to Heritage Woods who are ranked lower. Heritage then lost to Tweedsmuir, who lost to Walnut Grove in the final.
Overall a good list; I might have Heritage as an HM, Fleetwood a little lower given the small sample size, and perhaps have Walnut Grove in the bottom half of the top 10 or an HM as well.
Those are just my thoughts though! Well done
