I've tried tweaking the lumbar without much success. (Larry, thank you for the suggestion).
I found that the issue with the pain in the hip/leg/back was due to the narrow and very deep bucket design of the seat. Where unless you have the hips of a child or are very thin, one or both cheeks are forced up on one of the seat edges thus putting stress on your hips which telegraphs up the back and down the leg.
I tried to fill in the extra deep bucket with a folded towel and found that IT HELPED GREATLY! While I tried to get used to sitting on a folded towel, it became obvious that the constant adjusting and refolding would be an different type of pain, so I went for a more usable option.
I purchased some dense foam, similar to the foam the seat is made of. Cut it (several attempts) down to just the right size then had a vinyl cover made for the cover and have been using it for about a week. So far, it has been a very good fix that doesn't feel too odd to sit on and GREATLY reduces the pain in my hips/leg/back.
