After doing some reading i have gathered that they have almost the same top end as the TD04L but dont spool up as late as the TD04L (about 500-600RPM sooner) which seems to be perfect between the CT9 and TD04L.
Probably best if you stick with something more common, like the td04l. man, 500-600 rpm comes in a blink of an eye. That lower rpm boost start will be hardly noticable.
