Some good big man boards behind stock waves

Hey guys,

Our family is new to wakesurfing, we had a SN2001 for a while so we surfed once or twice a summer but not much, however at the beginning of the summer we picked up a 07 Supreme v208. We keep it pretty simple, using a Ronix wakeshaper, stock tanks in the rear, often a boat full of people. We've had a great time but we have a few bigger guys in the crew, one around 5' 10" tall, 240 lbs and another about 6' maybe 250 lbs. Are there some boards out there that work better for a big guy? They can both drop the rope right now but you can tell they're burying our current board, which is an almost 10 year old Liquid Force board.

I'd like to find a board to help these guys out, riding behind mostly stock waves. Any input is appreciated.

Thanks!
