Hi Jack,
Thanks for writing. There is a video on our website for the new QLR 16lb Weight Pockets, but the principles of how to attach remain the same for both old and new. The new 16lb QLR pockets can be attached horizontally along the waist strap or vertically. The older 16lb weight pockets can be attached vertically or at an angle forward. The key is to weave them onto the sideplate that is located on the waistbelt of the Transpac so they don't slip forward. You might have to play with them a bit to see what angle works best for you.
SOLUTION FINDER
You also have to play a bit with where you want them. Most folks start with weight pockets directly under each armpit. I am small, so I tend to like mine as far back as possible so I have more room on my waist for other items.
The clipper pocket and the crotch strap can go on either side of the waist/belt buckle. It is completely your personal comfort and choice. If you are right handed, then you may want to load your right side with the pocket so it is easier for you to open and get to things with your right hand. But, if you find it is in the way or prefer the left side that is fine too.
If you have a 1" crotch strap, you may like wearing it behind the buckle on the left so that the crotch stap portion that says on the belt is kept in place by the buckle. If you have a 2" strap, then simply place it wherever it is comfortable each time you don your rig.
Oh, and GCS cord...again personal preference. Your Trek Wing has 45lbs of lift...try diving it with the cord open. Do you roll, do you feel there is too much gas "roaming" around your wing? Then tighten it down a couple inches...do you have enough lift or do you feel that the wing is restricted from giving you the buoyancy you need during a dive or at the surface? Then loosen it up.
There is no right or wrong here. All of this is personal preference and will take some trial and error in a practice body of water to get the rig where you like it.
Best,
Kathleen
