I would prefer not to grind the indexing tabs off of my throttle control mount; I would prefer to drill holes in my new ProTaper SE bars so that the tabs can still fit in there and prevent the throttle from rotating on the bars. At this point, I'm fairly certain that a couple of roughly 1/8 inch holes (I haven't measured or anything yet) will not cause any significant structural integrity issues that I should be concerned about. So I'm pretty much planning on doing this. I just wanted to see what you guys think. I should note that I will have very strong HDB Ultimate handguards on the bars, which will connect from a bolt-mount on the end of the bar, to bolts mounting the other end of the guard to the handlebar top clamp. This of course should add structural integrity to the bars. So all things considered, I don't think I would ever need to be worried about the bars breaking - at least surely not unless I have a serious crash (as in, not while I'm riding the damn thing...). So anyway, let me know what you think people, thanks.
