Carbon seat post recommendation ?

In what way is that relevant to the discussion?

because you're trying to fudge the issue with comments about fitting a
bat with tires and a saddle. fact: aluminum hits further. therefore
there is less ke attenuation. if there's /less/ ke in a system, as is
the case with a composite or wood, there's /less/ for the user to
experience, whether that be the bat user through his gloves, wrap, etc.
or the rider through the tires, saddle etc. pretty simple.

Makes sense... except that an aluminum bat also *feels* better when you
hit the ball (less resonance or something)... at least to me.

You're trying to fudge the issue with a very poor analogy. That entire
baseball bat analogy is irrelevant.

To illustrate how this ISN'T a problem, imagine the flexibility of s
Softride carbon beam instead of a carbon seatpost.
Now it's kind of hard to tell, because everyone always photographs them
from the side, but aren't they wider than they are tall? That would make
them stiffer laterally.
In any case a Softride beam can't significantly yield to the rider's
weight other than in the plane of the bike. A sticking-up seatpost could
by bending sideways as well as backwards.
Unless the mount for the front end of the beam is perfectly rigid,
there will be some side to side (not much, but still there
nonetheless). Regardless, the point is that whatever movement there is
does NOT make the bike harder to control.

That doesn't make any sense. Obviously there is *some* side to side
movement even if your seatpost is solid steel. That doesn't mean that
*more* side to side movement might not be a problem even though a Softride
beam is stiff enough laterally.

#1 help : a better saddle
#2 help : larger tires
#3 help : double butted frameset
...
#27 help : carbon seatpost

1. Saddle - Brooks or Ideale
2. Shorts - thick dense padding
3. Shoes - Carnac
4. Gloves - gel
5. Tire size/air pressure - I use 23 or 25 at about 130 psi and can
tell no difference in comfort/ride/etc.
6. Double layer of cork handlebar tape - larger diameter fits hands
great and provides a little extra cushion I suppose

And of course these comfort remedies should be applied to a frame that
fits right. If the frame does not fit right, its hard to get
comfortable.

Question, would brand of tire do you use that a 700x25 requires
130psi? Do you weigh a lot?

I thought 100-110psi was about right for a 25.

At 165lbs, 90 psi is right. I run 65-70 in my 28's.
