if so fix your technique, if not so unlucky bud. i think they're like $5 for new springs though
O.P. hasn't responded. I'm with Uniin on this one. I see so many pedals set up way past 90 degrees to contact the batter. I would bet a shiny buffalo nickle that is what happened here. I've been bashing Metal sets most of my drumming life and have never broken a spring or batter head. However, it is quite possible you had a deffective spring with porosity defects in the metal from manufacturing.
