Hi Tom,
I have been using the Pentax XW's for about 15 years. I have also used just about all the other premium eyepieces sold over the past 40 years. Once you get things sorted you will find the Pentax XW's to be very easy to use and very comfortable to use for long periods.
The 10mm Pentax XW is one of the absolute best eyepieces money can buy and has been for about 15 years. Persevere with it. As a matter of fact the only eyepiece I have found so far that I like better than it is the 12.5mm Docter and its North of $1k. That having been said the DELOS are also very good and the equal of the Pentax XW's, with the only differences being minor subtleties.
Some tips to try.
If you observe without glasses, start off by winding the eyecup right up to the top to minimise the distance between the top of the eye guard and your eye. Slowly wind it down little bits at a time until you find the spot most comfortable. It's likely you will find the most comfortable spot is with the eyeguard wound right up near the top.

A very important tip is to learn to keep your head still and your eye in a fairly fixed position relative to the eye lens, when you're observing. You can't move your head around like noddy the clown and expect to comfortably hold the exit pupil with most long eye relief eyepieces. With short eye relief eyepieces its much easier to hold the exit pupil.
Keep at it and focus on the above points.

The 27mm Panoptic is an ideal low power finder eyepiece for a 10" dob. Compared to some other 2" eyepieces it has a small light form factor so it doesn't cause balance issues and optically its very good in 10" ~F5 scopes.
