By the way, as a point of reference: I am 6' 2" tall, currently 215 lbs. Everything being totally equal (drysuit or 7mm set up), just switching out my jacket style Scuba Pro X Glide Pro BC for the XDeep Ghost deluxe, allowed me to shave off 11 lbs of lead due to the buoyancy characteristic differences of the two rigs. Don't get me started on the huge differences and benefits in being streamlined. Night and day!
