I was die-hard Abu for years but have switched over completely to Lew's. I've used a set of Tournament MB
's hard for a year now and they're still working as smooth as they were new.
Me changing over to Lew's was not so much about the products being better than what Abu or Shimano offer, but because you can get a better reel for the price by going with Lew's. And they appear to hold up well to heavy use, which was my primary concern.
