Well, after doing the 1100 mile trip back (at least 700 of it yesterday), I can say without a doubt, that air cushion made a BIG difference. Riding there with my new memory foam after several hours, hurt. Then I put on one of those seat wooden bead covers. Felt good for a few hours and then felt like I was sitting on bricks. Way too hard. Then I slipped in my air pillow, and what a difference!
I've done many long trips on the stock seat and I hurt. Then I reshaped it; helped but still hurt. Then I've tried various foams; better but still hurt. But this particular thin air pillow left my behind never once hurting. Anyone on even a good seat will get tired of sitting when riding 10-14 hours straight day after day with just an occasional stretch, but what I personally want to avoid is, pain.
In another post I bought some bicycle padded pants to try. I can see that for me they don't work. Not enough "breathing room". My regular boxer shorts and that air cushion was much better.
The "trick" is to let the air valve stick out the seat so you can adjust it as you ride or at a stop. What I found that works best is just barely enough air to float you. Too much air makes the cushion "pillow" on your balls, the path of least resistance, but just barely any air just gives an equal push all over.
Anyway, for those that are interested in this thread, I'll try to get some pics later today. The pad does not raise the seat, because I took some of the stock foam out, but it did widen the seat a bit which helps.
Oh, if your looking for a great looking seat vs a comfortable seat, then you won't want to do what I did, but the seat looks good enough for me.
