I an new to this forum, so excuse me if I sound a little confused about this topic, but I have recently went and bought some new #10 O-Rings at the nearby Lowe's and outfitted them on some of my Vipers and Crimson Guard's. They seem to make the joints really tight and they seem to make the figures alot more tight overall. The problem is that I wonder if it is a mistake putting these new "tight O-Rings" on these vintage figures from the 80's because it might create alot of stress on the metal hook as well as the plastic that it wraps around on the inside of the figure? I am very picky about my figures and just wanted to replace the old worn out O-Rings with these new ones, but if it might damage the figures somehow in the long run, I definitely would want to know. Again, this might sound like a stupid question but if anyone could give me their opinions on this it would greatly appreciated....thanks!!!!
