to yoko, i have not experienced much problem in the way of bike seats, but i have found that the gel type does seem to help on longer distances.i have always favored the avocet gel seats,but most recently switched over to the selle italia flite gel that you mentioned. mainly i thought it had a better style. japan, wow, i was there visiting friend @2yrs ago, had an unforgettable time! anywat, good luck with the seat.
