Naw, I have a hate on for that guy... and arrogance. Some of my cynicism tends to bleed through sometimes. I worked with him once on a job, never again... fat lazy son of a bitch. #### the Slug we called him. Hint: it rhymes.
And yeah, I suppose there are dynamic courses and ranges you could take for real steel (now I'm remembering the dynamic carbine video by Magpul), and ISPC in Airsoft, but I stick with games rather than ranges, again, that's just me.
I suppose I should mention, I've got nothing against real steel myself, I think it's pretty nifty, but I prefer airsoft, for the aforementioned reasons.
But yes, you're right, they each have their own time and place and purpose, and as I said, there's little to no reason for mixture.
"War must be, while we defend our lives against a destroyer who would devour all; but I do not love the bright sword for its sharpness, nor the arrow for its swiftness, nor the warrior for his glory. I love only that which they defend: the city of the Men of Numenor, and I would have her loved for her memory, her ancientry, her beauty, and her present wisdom. Not feared, save as men may fear the dignity of a man, old and wise." - J.R.R. Tolkien
