IME, the best EP for Saturn in your scope is more often than not a good high contrast 12mm in a high contrast 2x barlow. Note that most 2x barlows will often function as 2.2x.
This yields a magnification of around 220x is high enough to see a lot of detail (just about as much as your scope can show you if you have a good keen eyesight), but low enough so that the image still looks okay in moderately good seeing.
The EP-barlow combo which I found gives the best view is 12mm UO HD orthoscopic in a 1.25" (or 2") Orion Deluxe 2x barlow. These barlows are especially well suited to planets with their unique internal baffling yielding the highest contrast IME. (I've also got Televue, GSO 1.25 and 2" barlows, and have used/owned most barlows, incl Powermates, on the market with few notable exceptions: TMB and Zeiss.)
My second choice is the same barlow with a 12mm Pentax XF. This EP is almost as good as the HD ortho ito sharpness and contrast (almost) while also giving you and your guests comfy eye relief (enough for eyeglass wearers) and a nice 60-degree wide field of view.
