Padding your pell (pool noodles, sleeping pads, etc.) will save your wasters a bit. You really need to be working with something that has discernable edges. Sticks are fine when you have nothing else, but there are particulars to how things work that you really need the edge there to see and feel what is going on. The wrong kind of padding can create a bouncy pell though. I have a portable one that is dangerous to put full power into because the waster is likely to fly back at your head! (I make my pells aggresive I guess.

)
Are you stepping with each strike? Pellwork is one of the best ways to get your feet in time with your hands since you have that feedback into your hands that tells you when the strike landed.
If your hands are hurting, you're hitting hard. Congratulations, that shows effort. I'm guessing you are throwing a zwerch that is causing much of the wrist awkwardness. There is a particular way to hold the hands that should be shown in person, or explained by someone other than myself. If you have access to Meyer 1570, it is in there.
BTW, when I said "opposite" I was refering to your statement about there not being much content on the site in regards to pellwork. There is quite a bit about solo exercises, so I turn much of that in to pellwork, thus there turns out to be alot of pellwork content even outside of the articles specific to it. I hope that makes sense.
Caveat: I'm just a novice, but have made (and am still making) most all the rookie mistakes.
