Yea, I can understand where people are coming from with this. It is I think, as was suggested earlier an individual thing, like buffeting & possibility even weaver birding. Having just completed approx 1800 pillion + luggage miles, with a couple 400+ stints included, I was fine with all three "anomalies" With regards to the "num bum" I wear a pair of gel padded cycling (lidl specials) shorts but I think the real trick is to move about on the seat as much as possible, not as easy 2 up but it does make all the difference in the blood circulation department.
