I have an 84" Bradco that I put a tooth bar on. I typically buy extended lip buckets and typically Virnig. However for a tooth bucket I think there are some things to consider. The times that you need a tooth bucket are for obviously hard digging. The teeth extend the lip of the bucket out further, this increase in tip radius reduces the machines bucket breakout. The Bradco that I put the tooth bar on is a shorter lipped bucket, but by the time you factor the length of the teeth you are essential at an extended lip configuration ( so if you put teeth on an extended lip bucket you are further reducing breakout when you need it the most). Your Cat I think has around 7K in breakout, which is factored typically with a shorter lipped bucket (provides a more impressive breakout number, which is common). To maximize what breakout you have, I would consider the length of the bottom of the bucket with teeth on it. If your working your machine in tough breakout conditions, it can matter.
