RE: MOKI RADIAL Care and Maintenence
I have both : with the Engel super silence 32*19 2bl they have great performance, with the 215 rpm = +- 4600, with the 250 = +5100, so I think the power from the 150 (may-be more ? ) I like more the sound from the 250 because he's more tuned, the 215 turns less 'nervous'. But if you don't need the maximum power the 215 is also good and cheaper.
