Rincon or Foreman?

Hello, I currently have a stock 04, foreman ES except for 26 inch mudlight radials. I have in mind to buy a Rincon 680. I do trail riding mostly with some mud involved but nothing very tough, prefer to go around really big holes. My question to you guys is this, will the Rincon get bogged down with the bigger tires and will I get left behind for my son to laugh at or will the Rinny be able to handle the slop?.
