yeah retics are the skinny guys of the "giants." i haven't owned any that size yet so i can't say for sure, and it also really depends on how heavily you feed them. but shooting from the hip, i'd say a 14-16 footer that was fed moderately would be about as round as a softball. i don't expect this guy to hit 16 feet. the breeder said his parents were on the smaller size for mainlands, but even if he does, he's not goin anywhere. lol
