jon m:ahh Tobin, you got me!!!!
i'm estimating using what i've worn in the past... i will actually be in the water this weekend to dial in my weight ( with your rig). i'll be using 22lb on the plate(maximum the pockets will carry, hopefully won't need it... the less the better) and the plate(6lb) i will also have a weight belt avavilable to add any needed weight. i finally have ALL my gear that i'll be using (congratulate me!) and i won't be renting NO MORE! so once i get dialed in, i won't have to adjust it (for local cold water conditions)
it will be fresh water this weekend (52F...brrrr)getting bouyancy down- so i think i'll get a pretty good idea where i need to be in cold saltwater (+1lb for every 40lb of diver and gear is what i've heard, is this accurate?)
jon m:i was probably over weighted in rental gear, but i don't want to spend my time in monterey trying to figure out how much weight i need (within a lb or two would be great). also, all my previous diving was done with a bc, and i have a feeling i'll be dropping a pound or two with the more streamlined/less bulky bp (less water displacement=less bouyant?)
jon m:if you could help or point me the way with the difference in weighting (real lbs) of a steel100 compared to an alum80 that would be great!
cinder4320:My Dive Rite Venture wing will not float my rig without me in it. That is if I am diving my HP steel 100, SS BP, and 6lbs integrated (in Zeagle weight pockets attached to BP). I don't plan on getting out of it though so I haven't had a huge problem. With the above setup and weighting I am wearing a 7mm farmer jand and a 3 mm jacket. Basically I think this happens because I am so darn bouyant wearing that much neoprene that my rig has to be a bit negative. Now if my drysuit ever gets here I will see how that work instead!
Do you forsee this being a problem? if so what sort of solution would you recommend? Just looking for opinions and discussion.

When you do a weight check this way, you have to calculate additional lead needed to offset buoyancy shift for gas in the cylinder, right?cool_hardware52:Jon,
Have you done a careful weight check as per my recommendations, i.e. eyelevel at the surface with an empty wing and a full cylinder?

Splitlip:Probably easier to do the check with 500psi. Then the lead he needs is what it is.
cool_hardware52:No not really.
What happens to a 7 mil wetsuit from the surface to 15 ft? With a 100 cuft cylinder he's typically going to use about 6 lbs of gas. A wetsuit that is ~25 lb buoyant at the surface will easily loose 6 lbs at 15 ft.
If you doubt this get neutral in a 7 mil at the surface and swim it down to 15 ft. Betcha need to add gas to your BC to stop at 15 ft.
When it's practical, i.e. in 5 mil and heavier wetsuits, I prefer to perform a weight check at the surface with a full cylinder. There are a number of practical reasons for this; you can do it at the start of the dive, you have easy access to spare lead, and one need not dump gas to reach "500" psi. Much easier.
With heavy wetsuit you might find the correct weighting for 500 psi @ 15 ft leaves you positive at the surface at the start of the dive.

Splitlip:We'll see. I am ordering a 5mil shortly. With my 3mm I did my buoyancy checks with 500psi and I was barely able to hold my safety stop. My 1mil on the other hand was pretty much dead on.
