My understanding is that normally the carbon component is cured in an oven, without pressure.
Perhaps this is the problem?
My knowledge of Carbonfibre component production is obviously quite different to yours, could be down to grades involved, perhaps.
there are 2 ways too design a rod and get equal stiffness, fast taper thin wall or slow taper thicker wall.
What about different modulus cloths, additional materials, variations in the layup of cloths, different types of scrim as well different modulus of resins.
having a thin wall means any bubbles will be a higher percentage of the wall thickness , on a slow taper thicker wall it is not so important as it is a lesser percentage of the wall thickness.
If the wall is thicker then there is more material, if there is more material of a similar type to the thin wall, then there will be a proportionally greater number of bubbles in the thicker wall so the effects are likely to be the same. Inclusions are a bigger problem and can affect any carbon component.
The pursuit of lightness is not always the best path. jim
Couldn't agree more
Recovery rate is far more important, but then that involves removing mass and increasing stiffness, finding a compromise that manages to tick all the boxes is the elusive holy grail of fly rods.
