Thanks all.
The lacing could NOT have made the saddle too inflexible, it already is too much for me! And if it is flexibility in the perineal area... No matter how supple, I don't want to bend cowhide with this part of my body! It would seem I'm very sensitive in this area.
Seeker333, I think you're getting more and more points...
I rebuilt my accidented bike (Swift folding bike) on which I had left my Flite (Gel Flow) on. I switched to another Italia on my main bike, built like the SLR but more supple casing, found it more comfortable. Having rebuilt the bike, I rode it... With the Flite. Why does it feel pretty nice now? A bit of sit bones discomfort sure, but it ends there, no pain, no pressure where I wouldn't want it, a wide range of positions to sit on, not slipping so I'd sit on my crotch... Maybe having lost weight helped.
I went to the lbs (hum, not the one I sometimes work for, he exclusively sells Brooks - almost entire line- and very low end large comfort saddles) to have a look at the Fizik Arione and other Italias. I won't buy another Italia, too close the ones I already have. And the Flex-Wing in the Arione? That? Flex? Italias flex more. They are hard as rock, but their shape at the rear is wonderful if you want more sitting positions.
It would seem that if a Brooks could fit, it would be the Swift (don't have a Swallow at the shop). And I absolutely don't care for it being "hard", I don't find Brooks saddles to be hard except on the shelf... That Swift hasn't seen 300 miles breaking in (I'd even say it has seen less) and it has support yes, but is not hard. Am gonna pay the boss a good bottle of wine and borrow is saddle for a few rides, see how it compares against my Italia.
Selle Anatomica are touted as more supple. No way for me.
Both seem good, Swift seems from memory a bit more comfortable on the sit bones, but I think the extra positions offered by the Flite may make me leave with the Flite. Which would be great: if I can get a Swift for a very reasonable cost, the Flite would be... free.
