It hasn't affected me, but I see what you're getting at, as we are influenced by what we watch, so the umpires will probably be less hesitant now to give someone out to a left arm offy. (I think the last time I was given out LBW was last season when a spinner pitched a disgusting half tracker, which i went on the back foot to smash over cow only for it to hit me on the toe, so I don't speak from experience...) Mind you, at the level I am playing cricket at currently, the spinners tend to be pretty slow, so you tend to have a little more time to play the ball, so less chance of LBW. We have given an awful load of LBW decisions this past season though, some which were not out. I think perhaps the DRS has caused this trigger happiness!
I think it has affected both spinners and pace bowlers, although primarily spin.
