The only reason to go to 2" is for wide field of view. Typically this is 65 to 82 degree AFOV in 18 mm and longer FL, so you want to look at eyepieces with at least 65 degree FOV or there is no real reason to go 2".
There are 2" that go down to as short as 4 mm focal length so you can achieve FOV of over 100 degrees, but they are VERY expensive. Many people only have one 2" eyepiece. I have two. And I would say most people go to 1.25" below 20 mm, but there are those who are 2" all the way to 4 mm.
My 2" are 70 degree (38 mm) and 82 degree FOV (20 mm). After that I am all 1.25"
If you have a preference for Celestron brand eyepieces, the Luminos line has 31 and 23 mm 2" 82 degree eyepieces
Also consider the Explore Scientific 68 or 82 degree line. I have the 82s in 1.25"
Going back to my earlier post (#14), even if you are not going to spend a lot of money on eyepieces now, plan out your eyepieces. Set magnification targets. And consider AFOV requirements. Finally your budget for eyepieces. You can easily spend more on eyepieces than you spent on the scope.
This will also help you decide what barlow you will want, 1.5, 2X, 2.5X or 3X. For your scope I would think 1.5 or 2X and no higher. There are some that will give you 1.5 and 2X. I have one like that.
Then you can decide if you are going to keep using the 25 mm you have now and add something lower or higher power now with a plan to replace the 25 mm later, or if you want to go all wide now and retire/sell that 25 mm.
If people are on a tight budget, I tend to recommend that people keep using what they have now and fill in the set with a barlow planned in for economy purposes. Then replace what you have once you have the rest of the set filled out or when you feel the need to replace. At some point you might retire the barlow too.
Right now you have a good 25 mm. So, is it really cost effective to replace it with a 24 mm? Only if you feel you need a wider FOV right now. That is up to you.
