My recollection is that the Saltrodder series is pretty much the same as the non-TL silver label series, so you could probably get a good idea of the action from casting a high index midflex 9'9 wt silver label (like a 7.5 flex).
I had a 10 wt saltrodder for about 5 years and loved it. Not super fast, but really cast heavy lines and big flies well, but had enough sensitivity to make catching smaller fish fun. I lost it overboard last year and am still p.o.'d about it...
