I have the 5/4/3 and it is a great suit. Easily the best suit I have ever owned (least expensive also) been surfing about 30 years. I have the access level 3/2 and it is an Ok suit, not great for early season but keeps you warm in the fall to a point. I am selling that one to get the amp 3/2. Hope this helps.
Oh yeah, I wore my first 5/4/3 to a frazzle in the first year of use (bought one size too big and the knees above the pads wore out and the strange folds caused by the oversize caused the tape to come loose) and they sent me a new one. Not sure if this is normal policy for them but they have been great to me.
i rocked my hyper flex 3-2 non sealed seems all winter long although it got chilly in febuary and i really only went out once a month any way i had fun with it i just put a oniel 2mm shirt under it nice suit warm fun
