The older IXS flows without the removable pads are my go-to choice.
Perhaps the chafing is to do with access to the removable pads on their latest ones?
If i currently kneeded nee pads, i would be looking at either the IXS flows (based on how good the old ones are, and how long they have lasted),
or 661 evo (based on how good the 661 evo elbow pads are).
I have some Sweet Protection bearsuit kneepads, which are pretty solid,but a bit hot and some ION k-lite, which are decent, but the removable pads are a bad fit. I’ve cut them down with scisors, but they are split, so i’ve ordered spares off bikeinn.
Also have some fox launch from when i got to BPW and forgot my kneepads. Tried on the medium, and they felt too tight, so bought the large- but i find i keep having to pull them up. They are the pads i use for uplift days, as they offer the most protection.
