Best Eyepiece for PST?

What is the best eyepiece for use in a PST? Do the number of elements in an eyepiece make a difference with this telescope. What about eye relief? Should a Plossl be good enough to see both sunspots and prominences?

I use Plossls with my SolarMax 60. Contrast is most important in my opinion. The widest true field you need is about 1/2 degree...
