If your arse is exactly the same width and weight as JB's, and you are the same height, have the same arm length, leg length suspension setup, back length and precisely the same aches and pains as he does, you
might find that his choice of seat will suit you perfectly.
In short, every seat is different for every individual........you may find that a pair of bar risers transforms your comfort, you may find that a sheepskin does the same, or a Tony Archer re-cover is perfect for you, or a Corbin is great but a Sargeant is impossibly uncomfortable.
All you'll get by asking that question is a load of replies from people who have, maybe, found what suits THEM.
The ONLY way of finding out what suits YOU is to try some out, unfortunately
PS you have NOTHING to lose from trying the simple, cheap things first........bar risers change the whole way your body, spine, coccyx and everything else relates to the bike, and you can buy them for 30 quid and sell them for 30 quid.
PS Sorry, not trying to be negative, just realistic
