My MAIN English (and for many years now) is an Stubben
I have posted the newest saddle acquisition I have made, a run-of-the-mill synthetic (and used) Wintec...I can say,it is far more of a secure seat for trails/ general-hacking, as that's why I got it...Where I ride now has little flat land, and trails are the other factor...so....
generally speaking, the size difference between English to Western is 2 sizes.
or, If your English is a 16, the rough equivalent is 14 Western...Mine is 18 English=16 on my Wintec
oh yea, If you look hard, you can find them used for around the 100-175 price tag...easy to clean as well...
Takes a bit of getting used to but, far more comfortable for the longer/hilly haul
