I had a professor in college who had a couple thousand hours in the -100. He said it was such a pig on hot days and with full load-out that he used to have to tie a bag of dirt to the nose wheel, its opening facing down and secured closed with a piece of string tied in a slip knot that was run into the cockpit. When the beast had chewed up all but the last couple hundred feet of runway on the takeoff run, he'd yank the string and dump the dirt under the spinning nose wheels to make the airplane think it was going off the end of the runway in an attempt to coax it into the air.
Anything worth shooting is worth shooting twice. Bullets are cheap. Life is priceless.
