The EP that came supplied with the PST should give you good views.
If you are not seeing any details try adjusting the doppler tuning ring and that should help a lot.
The Other EP you are referring to is better made to give you a lot more contrast and crispness.Try again with your original EP and get a good focus then adjust the doppler tuner ring to vary the bandwidth to reveal different features.
You should be able to see solar flares if there are any present as well as sunspots.
When you have the doppler tuner adjusted right you should see an orange peel effect on the surface of the sun.

I don't know if it's OK to plug or advertise here but just Google "Philip Pugh Astronomy". I've carried out extensive tests on the PST with a variety of eyepieces and the CEMAX 12mm is the best, both visually and photographically. I haven't tried any eyepieces costing over £100, as I consider them disproportionately expensive, compared to the PST itself. Indeed, there's no point in buying the 18mm or 25mm eyepiece, unless you are going to use the Calcium K version of the PST.

I have posted over 500 pictures of the Sun on the web and all were taken using a PST and digital camera.
