The 8 man level can make a big difference. I remember Rockford having to move up to A for a couple years and they won like one total game and was going to beat down city routinely. They dropped to 8 and was at least in the semis If not the finals the first year.
Most of the time teams that really struggle in class A still struggle in 8 man. 8 man is full of 130 lb 9th graders and soon to be 8th graders though, so teams have a better chance in 8 man. Maybe go 2-6 instead of 0-8.
