Among the positive feedback (thanks guys) I noticed a few posts on various forums saying the RayStorm and Rasa base are probably the same, so I thought I better clear that up. The RayStorm base is 56x56mm while the Rasa is 50x50mm and we changed the pin design to fine channels. The water channel design in the Acetal top is different too.
The RayStorm won’t be replacing the Rasa, but it’s our new high end block. The Rasa will remain in production for our kits and it continues to be a great block for performance/value.
