I'm glad you had a good experience
You always hear of the disaster stories on here for some reason. I really enjoy these MR markers, sometimes we all hit some problems but there's nothing a little bit of lube and know-how won't overcome.
I agree with the last part of your post totally, last fall playing some of the local scenario fields with my MRs, I've heard some of the kids ask to play with 'the guy with the machine gun'!
