I either own or have used nearly all of the eyepieces in questions, so let me try to share my opinions of each.
The 62-deg "aspherics" are remarkable eyepieces and perform better than anything that cheap should. I've bought a couple sets, and they're what my son primarily uses with his short tube refractor. They would make excellent medium power eyepieces and are a noticeable improvement over the MA26 and MA9 eyepieces you have (which also aren't bad, but the wider field of view is a nice enhancement of the overall telescope experience. I'm either lucky or have low standards (or both), but the 4mm really didn't seem that bad to me. I bought one set for $20 and the other et for $15, so if you make an offer to one of the sellers you can probably get all three for the same price as two.
I've been really happy with all of the generic Ploessl eyepieces I've ever purchased, with the exception of the "Series 500" ones (that are sharp but have a noticeably smaller field of view than other Ploessls). You can get a set of 32, 20, 12.5, 10, and 6.3mm Ploessl eyepieces plus a 2x Barlow for about $60 dollars or so. While the coatings don't appear to be quite as good as my more expensive Meade 4000 "yellow letter" Ploessls, they compare very favorably when actually looking through them. I've bought dozens of them to do with scopes I was giving away to people as upgrades over the stock eyepieces and they've all worked very well.
The Meade 8x24 zoom is nice. Really nice. It's also big and heavy which isn't a great combo with the Infinity 102 mount. However, it and a 2x Barlow cover everything you could ever need for the Infinity 102, which is a plus (I got one for my dad's scope). It won't solve your low power problem with the Dob, though, and at low power the field of view isn't much better than what you're already getting from the MA26. Certainly not as good as the 32mm Ploessl would be.
I also bought two sets of the 68-deg "red line" Svbony "Expanse" clones, one for me and one for my father's scope. They work really well with my scopes that are above f/6. With my f/5 Polaris 130 they're utterly intolerable, even with my incredibly high patience level / low standards. With my other scopes, though, they're awesome as mid and high power eyepieces, since the eye relief is generous. They work okay with the Infinity 102, though stars at the edge of the field of view may not be quite as in focus as the ones in the center. Compared with the MA eyepieces the field of view is pretty jaw dropping. Given the choice between all of the eyepieces above, my dad usually chooses to use them with his Infinity 102 (over an expanded set of MAs similar to your own and the 8-24 zoom). They're a little picky with eye placement and when looking at bright things (objects in the daylight or the moon) where your pupil constricts they tend to have blackout spots if your eye isn't in just the right spot. It doesn't bother me looking at other targets at night, though, but in the day it's really noticeable.
I tend to be pretty torn, myself, and with my ETX and the SCT I tend to fluctuate between using a set of 32mm-26mm-20mm-15mm Ploessls (with 3x Barlow) and using the 20mm-15mm-9mm-6mm "red lines" along with a 32mm Ploessl because for low power the 20mm 68-deg eyepiece just doesn't quite do it for me. For finding things I greatly appreciate the wider actual field of view of the 32mm Ploessl.
If you like the magnifications your existing eyepieces provide, I'd suggest picking up a generic set of Ploessls: Make an offer and you might be able to get it a few bucks cheaper.
Otherwise, I'd pick up the 32mm Ploessl and whichever of the others calls to you. None of them are bad eyepieces, so I doubt you'll have any complaints with them.
