The new pants make me look 20 lbs. lighter. Oh, wait..I AM 20 lbs. lighter (yea for me). OK, they make me look more than 20 lbs lighter. 
Another reason for me to hate them...I dont need to look like Im 150 lbs.
TexDoc, I'm not debating their comfort or anything like that. Heck, it was mentioned on this(or was it another) thread that we could just go out in crocs and a T-Shirt as long as we called a game, so why bother with looking professional, right? Same argument applies here. It looks like crap, IMHO, so why would we do it? Either way, respect your opinion, but I strongly disagree.
Not sure I have ever heard anyone say the bag was to "inconspicuously" mark a spot. Seems to me the purpose would be to "clearly" mark a spot. The spots we are marking are important spots for various reasons. No need to be inconspicuous. If you want that, why not make them "turf green"?
I'm going off the mechanics manual that stresses not to throw bean bags, just to drop them where the spot is. Seems to me TASO wants us to use them for ourselves, not for the fans, coaches, TV, etc.
