That's because unless there is a specific marking (as there is for

Trimming is a "feel" thing. You trim to relieve control pressures and
you
can't see pressure, you can only feel it.

But if you have an unusual load aboard, it would seem that you
wouldn't be able to feel it until you're already in the air. Unless
you mean that you'd be able to extrapolate from previous experience
with other loads.

Define "Unusual Load." ???

If you are way over MGW or loaded well aft of the CG limit, you're already
in a very dangerous place and no amount of trim will help.

I'd just like to be able to rotate more smoothly.

Don't pull so hard...

Seriously, for most GA aircraft, when you reach Vr, you pull just enough to
set an attitude and let the plane do the work. It sounds like the dynamics
of flying "heavy iron" are a little different due to the placement of the
mains versus the CG/CL but it can't be all THAT different.

I had to modify the contact points on the 737 just because I was plowing
the tail into the runway on take-off (and the standard model doesn't take
any note of this, which meant I was cheating for a long time and didn't
realize it). The B58 pitches upward even more quickly.

Your simply being too aggressive and over rotating.

I think if I can get good at putting the stick forward in just the right
way as the nose rises I will be able to rotate smoothly, eventually, but I
will try the trim stuff.

Like I said, don't try to horse the plane off the ground...set a proper
attitude at rotation and let the plane fly itself off the ground. Once you
are airborne and accelerating, then you can worry about pitch and power to
acheive a specific airspeed (Vx, Vy, etc...)
