I have one of these stephens pads - but with gell pads in front and back, but I would recommend the stephens pads.
I also have another saddle pad which is a fleecey pad, but has velcro strips along either side and pads that you can velcro in place - so you can have them at just the right point for your needs.
I hate the Wintec ones fwiw - I find they completely block any movement/feeling through the saddle and you feel as though your saddle is about a foot off the horse
(but if you want to buy one
)
The prolite rear riser is marginally better, but the best I've found is the Mattes wool rear riser, as it raises the saddle without blocking the feeling too much... unfortunately it is more expensive though.
