That would put him likely in our 115lb class. We have unlimited between the tackles (to a certain extent at 115lb, no limit at the 135 class, max age 12, had a few turn 13 depending when birthday falls) so these guys will see much bigger kids like they do in school. My son is on the 8th grade now so he played for the school in 7th grade and is taking a year off after a neck injury before going to high school.
I've coached for a long time and enjoy the interaction with families and community when you have it set up right. Winning is not the biggest part, but building up the boys for the next level in the game and more importantly, life is.
I've got a new laptop so once I get files transferred I'll post some pics.
