Having have purchased the S-Tek with the trim pockets, it’s is much easier to put weights in the trim pockets, with the wing OFF the back plate, and then assemble it all. I found that with the STA underneath the wing, you are simply fighting too much. With the ergo nuts, makes that process very simple

The stainless steel buckle on the pro harness looks like it would rub against ones upper bicep if it were setup like it is in this video. Anyone else notice that? Personally, I don’t like shoulder straps setup that way. On a backpack, I use the sternum strap to keep shoulder straps from drifting outwards. That’s the way the hydros is designed.

Installing trim weight pocket at the back of backplate can be a problem. For e.g. If you want to add just 2 pounds of lead in each pocket the wing nuts will tighten. But if you add 3 pounds of lead then the wing nut cannot be screwed. Is there anything which can be done about this ? One option is to add additional trim weight pocket on the backplate or add the trim weight pocket on the waist.

The trim weights CANNOT be put on without a specialty tool. My hands hurt from trying for 30 minutes and making a trip to Lowe’s to try to get it on. Engineers need to design the car to be worked on. This is a end user thing too, so not well thought out.
