Mine has always been boot over suit the few times I was not diving with a shorty. I guess i just got use to the shorty environment and the water puffung the boots. Now thats neo boots. rock boots definately over the suit to relieve the chaffing of the boot tops. I dive a harveys with seals and boots or not I am a michelan man when i get out till i pull on the ankle and i drop it seams like 50 lbs. Good thing harveys has good stiching. Dry suit it is a moot point for me.
