spectrum:I like to start with a full suit. I have a BARE Arctic 7mm and 5/4 Velocity. That I choose from along with a bodyglove 3/2mm.
Then I can add a beanie, a 3/5 hooded vest worn under or a 7mm hooded step-in sleeveless shortie worn over, 2 more BARE items.
I mix and match the suits and vests every which way. The 7mm combo is esentially the same protection as a John/Jane set except that I have 2 full layers in the shoulder where the John is usually only a strap for the bottoms. I prefer to have one continuous membrane covering my body such as a full suit provides. I can don all of it without assistance.
By not having the hood as part of the full suit I have flexibility in head protection selection.
I have been diving comfortably so far in water ranging from 44F to 76F. I hope to travel to warmer waters and will be diving colder water here soon. Probably going dry next year.
Don't forget the 3 most important things in selecting your suit, fit, fit and fit. It should fit like a glove. Slight compression is a good thing (it will probably loosen with use) but it must not interfere with your breathing. If it helps you exhale that's a red flag. You should have full range of arm motion and be able to bend over as well as you do in street clothes. If your proportions do not allow for this in an off the rack suit there are plenty of fine custom options available.
Water is not an insulator it conducts heat from your body 25 times faster than air. Your body tolerates the water that enters your suit. The suits job is to minimized the exchange or flushing of that water in the suit which is heated by your body. The suit via neoprene rubber, especially the gas bubbles contained there-in provide the insulation component, this component will diminish with compression as you dive deeper. As the suit ages some of this gas and the warmth it provides will be lost. If anything the suit will feel looser due to thinning/flattening as it compresses with depth. A too loose suit can pucker into folds and deliver welts from suit squeeze.
That's probably more than you wanted to know but I was on a roll.
