They are hard pressed - built to last but unfortunately the middle is not powerful at all.
Of course others will disagree but this is my experience.
This is utter bs. I had a Icon 606 that went pretty much instantly and has been the best bat I've used beating Newberys, GNs, Pumas, SAF etc. My new one hasn't gone as well yet but I'd still say it goes better than most shelf brands.
I've used a fair few bats from each brand and I still prefer GM, whether that's because of various factors that suit me or because it's how they're made.
I think you can't go far wrong with GM, the consistency from 606-Original L.E will be good.
