Wanted to report back now that I've had a few opportunities to do some stargazing. Overall, I'm very happy with both purchases and would recommend them if you're looking for a fairly inexpensive upgrade. And I will likely be able to use these should I upgrade scopes down the line. In my mind, a good investment either way. Here are my thoughts on each:
1) The diagonal was worth every penny. It's a perfect fit for the scope, is well built, and lightweight. The view is much brighter, crisper, and sharper. So happy I made the switch.
2) The eyepiece is nice as well. The FOV is amazing compared to my other EPs. I am having one small and unexpected issue, but it's not exclusive to this particular eyepiece, but most wide FOV EPs. It's impossible to shoot a pic using my phone. I'm struggling, even with a decent phone mount. With the naked eye though, it's really nice, clear, and sharp. Side by side, there's no comparison to the 10mm celestron EP that came with it.
My biggest gripe with my set up is the mount. It's extremely difficult to find and manually track, even the moon! Planets? HA! Holding it at set points is nearly impossible due to the ineffectiveness of the screw lock mechanisms. Even if you try and overcompensate and lead the planet into frame and tighten it down so it doesn't move, it slowly begins to sag into a different position. I don't remember it being such an issue a few years back, so perhaps it's gotten worse over time.
Here's are a couple of shots I took Tues/Weds this past week. The "Snow Moon" is really bright right now, but figured I'd still share. And as I mentioned, please excuse the poorly framed shots, I'm still trying to dial in my phone mount: https://imgur.com/a/dleuN0K
