Ok. Mr. Drumstix... lol jk. I had that problem forever. use barrel shaped tips. Acorns and ovals chip more. also try and take it easy on the cymbals, this is where mine broke the most... hit with the side of your stick instead of smashing them hard with the tip. :mrgreen:
i usually chip the tips of my sticks on my ride cymbal. I dont think i have ever chipped them on crash cymbals. i use pro-mark's japanese oak and the tips seem to hold up pretty good, if you are playing rock or any style that consist of hard hitting it is almost expected to chip tips and break sticks.
