well, from a durrability standpoint, I don't forsee it cracking on you from things like sitting down. the butt plate I have is plenty flexable. I was able to bend mine a fair amount with no ill effect.This is my first armor set, so I have little frame of reference. Only tear or anything I've had was my own fault, pulled my lid off by the chin and my head got stuck. about a 1/2" tear in the chin, easily fixed with a strip behind. Buffed the front with rubbing compound, and it's 100% invisible. again, my own fault. Another nice thing is that if you do crack it, or screw up the trimming, it's easy to repair and repaint the area. from what I understand, If you mess up ABS, there's not much you can do to cover up any mistakes. Again, this is my first armor, so I don't have anything else to go on. I can only say I'm very pleased with mine. I do want to say that I am a model maker, and painter prior to doing armor, so I do have alot of painting experience, and experience working with styrine, so my opinions may be different than someone who's new to doing hobby work. So take what I say understanding that what I think is normal work for a project may be alot more work than someone else is willing to put into it. Heck, I've spent 3-4 hours just painting eyes on a mini before. Hope I'm being helpful.
