While everything in this thread is interesting and useful, the real question in my mind is "is there something better than what I am riding now that would work on my existing bike WRT chipseal". An answer to that specific question is actually useful to me whether or not the resulting ride is 'comfortable' on chipseal. Since chipseal is only a small'ish portion of my riding it is a trade-off and there is a bigger trade-off (possible bike change) where this answer is useful (even if it is negative). So before I head off into new bike land (a place that I am not anxious to go) I would like to know how much of this problem I can (or cannot) solve on my existing bike.

Thanks.

ps. The actual width on my 23mm 4000s ii's is 25.5mm.
