now there are 2 Mayers (brothers) and one has a rep that's not what i'd be comfortable doing business with. since i don't keep up with the details i couldn't tell you which to go with Rocky or Rick Mayer brother.
i've stuck with Russell.
I've had two Rick Mayer saddles and three Russells. Rick Mayer is a great guy and a critical care nurse, so his grasp of anatomy and physiology is way ahead of any other seat builder that I'm aware of. Rick's saddles are also a good bit closer to a 'stock' appearance than a Russell, if that's important to you. Both of my Rick Mayer seats were built during "ride-in" appointments and Rick did all of the work, from shaping the foam to sewing and installing the cover.
Despite living just a few hours from their facility, two of my Russell saddles were done entirely mail order - I shipped them the pan, filled out their order form/questionnaire, provided the pictures requested and got the seat back from UPS. They were both outstanding seats - never had a moment's discomfort on either one and I rode multiple 1,000 mile days on each. I have had one seat built on a "ride-in" appointment at Russell and it is not quite as good as the others, but still very, very good.
My experience has been that the Russells are slightly more comfortable than the Rick Mayer products, probably because of the wider design and the use of the spring. I see no reason to do the "ride-in" process at Russell, because they do such a good job at building a comfortable seat without having you and your butt present for construction and fitting,
Leather is nice and rides a little cooler than vinyl, but I opted for vinyl in the 'large rectangle' design for my most recent Russell and it's just fine, probably because there are some seams to provide some cooling airflow. The vinyl seat in the 'half-moon' design is a little warm in hot weather - it has very few seams and is very weatherproof (which was the idea), but it's a little warm. I'll probably get a leather seating surface with the large rectangle design when I have a saddle made for the FJR (which will be the next group buy opportunity).
