I might suggest some gatoraid, lots of water, poppers and some whiskey shots for added energy! I'm sure it would be an all day and night event wtih that many but my money is on you my friend!
wow! that sounds like one hell of an amazing birthday party! Happy Birthday man! Definitely go for the 100, if you can manage 76 you can take on 100. Sloppy messy holes just mean less lube needed.
