Consider weight benefit ratio, carry x ounces for 31 miles to use them for 2 minutes maybe 3 times?. Unless you have some special condition that requires pads I would suggest the are not necessary. The couple of sections that require a trip under the boulders is mostly scrambling across lots of smaller rocks so pad are not really that helpful.
One suggestion, do Icy Gulch in Randolph as a day hike in CW direction , its a great tune up for the notch. I tell folks if they like the gulch they will love the notch if they don't like the gulch , they may want to reconsider the notch.
