Depends on much really, but how much you want to spend, where you balance protection vs all day use and whether the things actually fit your bodyshape are the biggys. Pads that are a bit sloppy fitting won’t stay put on impact when you need them.
You’re really going to have to visit a lot of actual shops trying things on/borrow from friends/risk many weeks of returning things to the internet.
I’ve just gone from 661 Rages (like Kyle Straits) to POC vpd 2.0’s and the difference in comfort and fit is astronomical. That said, the 661 knees have been tested many times over the last couple of years and have certainly not been a waste of money. Nukeproofs often work for people but can be a tad sweaty for big days.
What I would say is make sure the elbows feel natural. If it feels like you have hardback books taped to your elbows you’ll never be wearing them when it would help. 😉
