Do you routinely launch the boat at the same ramp?

What are the conditions there?

If the water gets deep pretty quickly, the boat will float free from the bunks
without a problem.

If you launch at places where the water is more shallow, rollers have some
advantage. With rollers, once you have established at least some buoyancy you
can often *roll* the boat into the water.

If you go with rollers, put as many rollers under the boat as you can. It is
true that bunks will support the boat better. Try to adjust the rollers so that
they are under the stringers, and remember that there is a specific risk of
"hook" at the transom.
