Twy E isn't technically a high-speed. I wonder if they thought it was.

Have you ever seen a -700 land at EYW?

The point that Ad Lib was making was in regards to the 737-800. The 700 is capable of the short runways while the 800 requires a little more work. As mentioned, the 700 Vref speed is usually about 135 while the 800 Vref is 150. At flaps 30 and autobrakes 3 the 800 requires 6700ft vs 5600 for the 700. With the high ref speeds and mediocre brakes the 800 just simply doesn't slow down and stop like the 700.

The reason the -800 requires more work is not due to "mediocre brakes" but rather, as you mentioned, the higher approach speeds. The brakes are very effective, they just have to dissipate a lot more energy.
 
Autobrake 3 works fine as long as you get them off by 80 or so. I do not recommend MAX on a bare and dry runway.
 
NAV Canada reported, that the airplane exited the runway at a speed of about 70 knots and came to a stop between taxiways E and B2 with all gear off the southern edge of the paved surface. At the time of occurrence there was heavy rain and winds from the south at 15 knots gusting 20 knots. http://avherald.com/h?article=4340b3c3&opt=512

Thats not really a nose wheel sliding off a high speed if you ask me.....
