Sent both my seats to Tobin, tracking # says they got there yesterday. I called and talked to him twice. He said that the seat is built to your individual specs. Thats why he wants your weight, waist size etc on the order form. He uses different denisity foam based on your weight, also the riser is altered based on your size. The same seat for a 5'8" 170# rider will be different than one for a 6'4" 250# rider. He cuts the foam down to effectivley widen the seat so it supports more of your butt. Less pressure on those couple of hot spots.
My biggest concern was the 1.5" drop, didn't want to give it up after going to the Buell Pegs. I have the Helibars and am pretty comfortable except for a PITA after about an hour and a half. All the 6" + guys that I've seen post say the lost height is not a problem. Will know for sure in about 10 days. Besides, it's only 325 bucks, errrr make that 425 ('cause a bought an extra seat to send to him) already know it will look better than stock, so that's my fall back justification if they suck. LOL
