Wow, some of the injuries you guys have suffered is insane! I've only been playing beer league for about 3 years, but have skated for many more.
I've had several cuts and bruises from pucks, sticks, and even a skate balde once playing outdoor shiny. Nothing that crazy.
The worst injury I had was 2 summers ago, I got laid out 3 shifts in a row from an open ice hit in a non-checking summer league. The first 2 of them was from a teammate who wasn't looking as we skated Into each other at full speed! He was bigger than me so I took the worst of it. My back was pretty messed up that summer, had to go to physio for like 3 months to get it sorted out, still tweak it every now and then.
The funny thing is that I wear full gear, even more than most guys (Shotblockers on my skates for full armor, full cage, even added some custom padding on my shoulder pads to cover gaps on the lower front ab area). I'm usually OK from most pucks and sticks, but I've learned that hard hits from bigger boddies can be worse if your head is down lol.
