Saddle issue

saddles ...pah...I've a garage full of them....currently on a Fabric Scoop Shallow Elite....comfortable enough for 4-5 hour rides....but I tend to squirm around after about 3 hrs and stand a lot, move position, adjust the shorts, pad etc...just can't find that holy grail saddle...

As others have said, saddles are personal and the only way is to try, however having just been through the same process, here is my tuppence worth. I recently bought a Scott Addict, and it is set up quite aggressive. I found the stock saddle to be sitting between, rather than under, the sit bones. When riding on the drops, the weight went onto the front end of those bones, where they meet under the perineum. Not good. I then took a Fizik Antares on test, and still found the saddle to be between the sit bones, and when on the drops, compressing too much soft tissue. A sit on the Specialized test pad showed that my sit bones are wider than average, and the shop recommended a 155mm width rather than the 143mm which most folk use. Specialzed offer a 30 day no quibble swap or credit voucher for the value of the seat. In theory you can go through their whole range, 30 days on each! I took the Power Expert, which has a short nose, wide cutout, and wide flat rear. My weight is now firmly on the sit bones, and even in the drops, no pressure on the soft tissue, but its early days yet. They also offer the Ronin, which has similar rear profile, but a narrower cutout and longer nose. Which one you go for depends on whether, like me, you sit on the back of the saddle all the time, or move about a lot and like to put weight on the nose.

Those Fizik test saddles, they're bright yellow, right?  There's no way a yellow saddle can be comfortable, it just can't.  My arse would be blinded by the colour, that's before we worry about any other aspects of its design.  It won't work.

The Planet X Superlight Team saddle is pretty flat.  I think it's modelled on one of the Fizik range.  Good value too at about £20. 

Fizik arione and Antares are quite flat. My fave flat saddle is the fizik Kurve (chameleon) although I've never seen a test version of this. I dislike curved saddles but strangely I'm starting to get on with a lovely and slightly curved Fabric ALM after a few hundred kms. Saddle angle makes a bike difference on curved saddles so take your time getting it right 

As others have said, saddles very, very personal.  You may even find that between two saddles that appear very similar, one is great and the other is awful.  And losing/gaining weight can mean your favourite saddle is no longer right!

That said, a couple to think about:

Specialized Ronin (various other Specialized too)

Selle San Marco Mantra

But with all, I would recommend a proper length ride to test.  A saddle that feels great for 30 minutes can feel awful after 2 hours. 

Oh, and the saddle positioning can make a big difference too - too far forward/back/tipped up/tipped down can all make a difference.

Good luck!!

Perhaps you may need one of these... It's worth a look, but the weight might be an issue for you.

If you have a Specialized store nearby it might be worth having a look. They also have a few flatter cutaway saddles and do a saddle fit and try-and-buy scheme. There's always the saddle swap thread over on Bike Radar too, more random but bit of variety.

I think that saddles are a personal item on any bike, I'd what suits and is cormfotable for me might not suit anyone else or visa versa, but like yourself I prefer sella Italia saddles,

do you not have any local bike shops were you can see the saddle before buying?
