Simple answer is, if the 45 is available and not going to break the bank, an ounce of prevention is worth a pound of cure.


The only problem with this philosophy is that the ounce of prevention is causing you to lose Pounds per square inch......That larger than needed wing will produce greater drag, potentially resulting in higher SAC rates. My philosophy is to keep your profile in the water as tight as you safely can........too large of a wing can be just as problematic as one without sufficient lift capacity......for singles, especially aluminum singles, a 30# wing on a properly weighted diver is sufficient.

DUDE the understand what the wing is doing. If properly weighted then all your wing is doing is offsetting the bouyancy lost by the suit + 6 lbs of air lost (in a single tank). Unless you've got lights, reels, stages, doubles, bells and whistles then what I've mentioned above will be the case. So if your drysuiting it then 30 lbs will be WAY more then enough. If your wetsuiting it then the only way you are going to get close to maxing out your wing is if you take a super thick 7 mm Wetsuit down to shall we say DEEP. In this case it may loose up to 20 lbs in bouyancy plus the extra that you are carrying for lost air (6 lbs). So your wing needs to offset 26 lbs. Being a 30 lbs wing it will manage great.

Alpaj,

I don't know about that number. I have dove in several wetsuits of varying thicknesses and layers, and drysuits........I don't know that I have ever seen a 20lb bouyancy range in my suits at any depth. If you are weighted neutral-slightly negative with empty tanks at the surface......the 30# wing will be great.
 
thanks for the info both of you :) still trying to learn more about negative weighting and how to add it all up to find out what i need(like an al80 at the end of the dive is 4# pos so i will need account for that at the begining of the dive with 4# more that what i need then?).. any suggestions or links?
 
thanks :).. oh yeah would you happen to know what bolts are used usualy to attach wings to backplates.. if its anydifferent DiveRite DP and Oxycheq 30 wing
