They're all Columbus tubesets though - anyone know what the comparisons would be in Reynolds?
I made some wild guesses based on comparing tensile strengths...
Aelle = 531 / 520 / 525
Cromor = 531 / 520 / 525
Thron = 531 / 520 / 525
Brain = 631
SLX = 631 / 653
Neuron = 753
EL-OS = 853
Interestingly, he thought the SLX felt soft, the Thron absorbed bumps best, and the EL-OS stiffest and "felt" nicest. But he was unable to differentiate much at all between the feel of Aelle / Cromor / Thron / Brain or Neruon... Only the SLX and EL-OS stood out at all.
