I just placed an order for an Avid Benchtop Pro 2424 and am looking for which Clearpath servos to add to it. Since there are only minor differences in price among the servos, I'm leaning towards going for a more powerful model. The question for me now is whether to go for a high torque model in the lower max RPM range or a lower torque model with a higher max RPM. I will be cutting mainly wood, ABS plastic and aluminum with the machine. Speed is not too much of a concern, but having it is nice. The servo models I'm looking at right now are:

CPM-SDSK-3411S-ELNd (638 oz-in peak, 150 oz-in cont, 2320RPM) https://www.teknic.com/model-info/CP..._voltage=75VDC

CPM-SDSK-3421P-ELN (547 oz-in peak, 164 oz-in cont, 3070RPM) CPM-SDSK-3421P-RLN https://www.teknic.com/model-info/CP...del_voltage=75

CPM-SDSK-3421S-ELN (1,094 oz-in peak, 288 oz-in cont, 1410RPM) https://www.teknic.com/model-info/CP..._voltage=75VDC

Any insights as to which of these would fit best would be greatly appreciated!
