I always heard ppl said stage2 stage 3 stage4 I/M......what's the difference?
OHHHhhhhhhhh yeah. Your right.Ryloth said:Actually I believe the Stage I is the just the lower IM, the Stage II is just the upper IM and the Stage III is both the upper and lower IM.
I could be wrong though, but in either case the Stage II IM is no longer on their website and NGM may not sell it any longer.
