I've had the same delema you have now
if you go rpm then if they break wich prob wont happen they replace them for free
i would go with alum or tita skids I've had better luck not breaking other parts with the metal skids :thumbsup:
RPM anyday of the week if you go metal make go with TI not Aluminum The Aluminum bends to much skids are actually a good place to use ti becaue they are more likly to no bend and spring back to shape. X
