Since I have a database of most of the summer tournament data from the U12-U17 boys, I assembed that into a table with some info about the median strength of the teams in the tournament division (last year), numbers of teams in the division, along with tournament date and place.
Go here and then click 'Tournament Guide' in the top nav bar.http://www.lastplanetranking.blogspot.com
It's a pretty big table. You can sort by clicking the table headers but it might be easier to download the comma-delimited files and open in Excel (there's a link to do that on the page with the table). You'll need to look up your team's 2012-2013 (last season) B00 (yes, B00) strength. The median strengths shown are B00 strengths, so that all teams (6 age groups) are on the same scale. Once you have your team's B00 strength, you can look up all the tournaments and divisions near that strength range. Tournaments mainly in WA & OR, but there are a number of higher level CA tournaments there too.
