I have tried several, including Sargent and the two piece Corbin, which is my fave.
Longest trip so far: 11,200 miles in 12 days. Not a typo. Including rain, some hail, 100 degrees+, NYC and DC midday traffic, many back roads, tons of slab flying, and a bunch more stuff. As you can imagine. Just over 1500 miles in one 24 hour period.
Changing seats is not enough. Even if you get risers, peg lowering, crash bar mounted auxiliary pegs, etc. I have all that too. My secret remedy is EXERCISE. Treat long distance riding like an athletic event and TRAIN a little for it. Double your maximum distance in comfort. Yes, I was a bit sore anyway.
