First, great job for doing your research first, that's so important with any pet that unfortunately there's not enough people doing it. And welcome.
Second, I know you already said you knew not to use pellets as sole diet, sorry if this is long, but it's my personal experience in regards to research & getting my gliders.
I found that after thorough research on gliders that it was very confusing at first to know which side to trust with so much conflicting info on the internet, especially when it comes to diets (along with some other factors). I have a friend who has had 2 sugar gliders between them both for about 3 years that she got from PP and sticks with their diet, she swears by it. So, that's what I originally did for the first 6 weeks about when I switched to one of the recognized diets listed in the Gliderpedia.
Why did I switch? After actually joining this forum I noticed photos of gliders that were fluffier than mine, and I didn't realize what "crackling fur" meant until I saw photos of before/after diet changes. My girls have "crackled fur" and are not as fluffy as some of the ones I've seen on here, so I thought maybe I could be doing better for my girls. Even though my girls appeared & acted healthy (they were a little chunky when I got them, but was told they ate a lot of meal worms). I just feel that good health is reflected in an animals coat, so I wanted mine to have something better. My girls loved their pellets though, so I give them on most days (not every) about 10 (5/glider) usually in the am when they've eaten all the main meal they're going to (usually all with exception of f/v mostly fruit they don't care for) they are scattered around in their toys for them to forage for. The only other treat they get, a few days/week is spoon fed fruit blended yogurt (w/o aspartame).
I chose for main staple the original HPW, because that's just what was easiest for me out of recognized diets, there are several to choose from, so it's a factor of convenience to make & serve as long as they like it and will eat it. So the important factors in choosing would be:
1. Recognized diet
2. Gliders like it and will eat it.
3. Most convenient for you, because you'll have to stick with it.
After you have chosen your diet you can follow the fruit/vegetable suggestions or instruction included in particular diet.
I recommend reading the ingredients, instructions on mixing & storing, and serving. These will help you factor in what's more likely that you can be consistent with.
Now, as for the pellets you mentioned, I think there is a chart that lists different brands, so maybe it's on there. I know only how to copy & paste

Some people leave some dry/pellet food in the cage at all times or during the day, some others may use for foraging treats, and many others don't feed any pelleted food.
Last note, my girls have been on the O HPW diet for almost 10 weeks, I haven't really noticed a change in their fur per say, but they love this diet and I'm going to stick with it as long as they do and are doing so well with it, and it might take some more time to make a difference.
