You shouldnt be stripping spurs like that- are they worn down evenly all the way around, or are they just 'flat' in certain spots, or chipping teeth etc?

RR steel spur should be an improvement, but only RR can tell you if its hardend or just plain steel- the RCM pinion will eat it alive in next to no-time at all otherwise, seen it happen a few times with some brands of metal spurs...
