If you observe with your local astro club you will be able to try all kinds of combinations without spending any money - so I suggest doing that! If you were in my club I would pop your 13mm into my 3x TV barlow, and we would give it a try.

I have the stock 5mm and 20mm eyepieces that came with the SkyWatcher and I have an Explore Scientific 11mm 82 degree eyepiece on the way.
What about getting a decent 3x barlow to work with the three aforementioned eyepieces.
That'll give me 163x with new 11mm ES, 360x with the stock 5mm and 90x with the stock 20mm.
By the way, I still don't know the difference between a plossl and an an eyepiece Wikipedia says they're one and the same?
Now - to research plossls. Does it ever end?

The 163 would probably be at the resolution limit. I'd be more excited about the views of open clusters and star fields with the 54x of the 11mm unbarlowed. Your best planetary views will most likely be in the 120x ish range.

"Plossl" is simply the optical design for an eyepiece that Mr Plossl came up with a long time ago, and it is the basic eyepiece that everyone starts with. Most on the market are made in China and are fine, but there are more expensive better quality ones available (eg Televue). However, most of us move to other eyepieces for wider views or more eye relief.
I'd suggest to wait and use your ES 11mm before buying anymore eyepieces. After trying that you will understand more what other eyepieces offer.
