Hockey helmit for rock climbing

Just wondering what opinions you have about using an HECC certified hockey helmet for rock climbing. May sound a little goofy but I'm thinking it could be a temporary solution while I save up for a legitamate climbing helmit. I'm slowly getting into trad and don't really have enough saved up to buy everything in one go. I grew up playing hockey so have tons of old helmets lying around. They are definitely way more robust than a cycling hemet and offer protection on all sides (I'd probably remove the face cage though haha).

Much better than no helmet and you will look bad ass. Win-win!

Infinitely better than no helmet but I bet if you posted on the used gear forum you’d find one you could afford. 

Keep the face shield on and never worry about cheese grating your face on slab again!

Go with the face shield instead of the full birdcage, helps keep chalk out of your eyes while belaying and pieces from hitting you in the face while bounce testing aid placements, but still allows you to briefly grip the rope with your mouth while making high clips

Do you plan on a fight breaking out while you're climbing?   

Better than no helmet!!

Seen a guy at potrero climbing in a ski helmet. Again, better than no helmet but it appeared to be very hot to say the least
