The alphason tends to like lighter bodied cartridges. Or, to be more specific, cart bodies of the right composition.
Since you are familiar with the lack of head-shell twist available, you can negotiate the alphason's curves of use.
the alphason is not all that damped, but it does not need much damping, due to it's low mass, and aspects of self damping. It's damping capacity is effective when handled within it's range.
Cartridges that work well with the rega arm may introduce too much energy into the alphason. And thus a bit more color than one wants.
This may help a bit:
