Very comfy for me - and yes they squeak.
Reason for me it that Fizic sensibly ignores the trendy "slot in the middle" thing which has made so many other saddles flat, and so puts all the pressure on two very small parts of sit-bones (which very soon gives me arse boils..).
The other really comfy saffle I have is 1989 built solid plastic factory spec GT. It's got no padding, and is narrow but a very similar shape to the Gobi in cross section.
It's the cross-section which is important, and irritatingly that's one thing which is very hard to get without measuring and trying. Before I found my Gobi, I used to go into shops with a cardboard cross-section template modelled on my ancient GT saddle.
It was soon clear that the Gobi was the only one with the necessary "hump", that didn't compromise itself on the trendy altar of the perineum.
