How would something like this perform on DSOs in my 130p?
Yes it will perform, just probably not significantly better than your existing eyepieces.
A small scope like the 130P is still a small scope, not that there is anything wrong with small scopes, but the main limiting factor with any scope is the aperture.
Eyepieces make a marginal difference at best. For example in my kit I have a 10mm Ethos (cost at present is around $800 - $900) and I also have a 10mm plossl that came free with my first ever scope. I have done the exercise of viewing an object through both eyepieces. Sure the Ethos has a massive field and the plossl does exhibit some aberrations at the edge and the eye relief is easier with the Ethos. But as far as how the object I am looking at is concerned, not much difference.
The lesson is that chasing "performance" by buying eyepieces is not necessarily a winning game. Good quality eyepieces at the top end are worth it in my opinion, but only if you understand what the true benefits are.
