I love my Inform RL WSD saddle...so comfy that I don't even know it's there...its very firm and supportive, not spongy at all, no pressure points- comes in 3 diff widths so my sit bones are right where they need to be. Feels great, even for all day outings. I use it for mountain biking; I have been riding this saddle for over a year and wouldn't love my bike as much without it.
I don't know how different it is from the RXL...but maybe worth a try?
