What can I say. Bombed two stages and pretty much took me out of the race. I had 5 other great stages with three stage wins but the two setbacks cost me 100+ points.
I don't usually load up my magazines to 29+1 because I don't want to stress my plastic grip and cause another crack but it was definitely useful for me in the 30 round Stage 2.
