Steel can be a ADVANTAGE, where are the iron workers and welders. Do research! Roids to us is TRASH but we expect it for others in there Keep so be at OWN WILL.. Plexi-glass server the same purpose as GLASS, but work differently, being the plastic material but if it breaks, which one will do more damage? I'm ole fashion and the game was about the BEST SHAPED DOG and still the same, and putting a Steel Tooth is not best to me. We fight chicken, "BONE SPUR", so what's wrong with going Natural, Bone Teething? OH! One more ? for my fellows, Can I implant a IRON JAW and still compete? To me it's the same..
