I also have a +35 year old Brooks Pro. I rode it pretty hard for about 25 years. It is still in great shape and is on my PX10. I used it in all kinds of weather except for winter training. I sometimes used a little more weather resistant (cheaper) saddle. Putting any kind of cover on a saddle does not help comfort. I treated my saddles both top and underside with "Snow Seal" which generally made them impervious to water. I quit riding the Pro about 12 years ago when I found other saddles that were more comfortable for me.
