I am with Macdoc. For most riders in most situations, the only downside of ABS is the initial cost (which on a used bike approaches zero).
If Iceman86 had ABS, he would have been posting about his close call instead of his banged up bike. People can say they practice threshold braking and could beat rossi with their eyes closed, etc etc but when you have a huge chunk of steel in front of you and think you are about to die, your hand clamps down for all it's worth. Even if you were perfectly on top of your game, changing road surface, tire temps, trying to turn, looking around for a hole etc. all use up your available brain power, there is not much left over for perfect brake modulation (especially on two separate braking systems at the same time).
