I've received a refoamed seat yesterday (seat was done in just 3 days!) and what a relief! After riding with it this morning i can say it makes so much difference. It does make it higher as expected slightly altering riding position. I feel as if i'm more leaning forward but same time lighter on arms. I'll need more time getting used to this new position but overall am well chuffed. 60 quid well spent.
P.s. thx for the pics Jeff, got the same design as yours with non-slip.
