liberty gears pros and cons

I blew 3rd gear out of my liberty last week(8th pass on the liberty gears) not happy! I raced with a slick shifted trans I did my self for 3 years till I burd up the clutching teeth in 4th gear and it got real hard to shift into 4th, but never broke a gear. I think when liberty is welding up the gears they are taking the heat treating out of them and not putting it back in. I am putting the syncroed street trans back in(witch has taken a beating on the street for 10 years with no problems)and I doubt I will do another liberty, to expensive for the longevity. Next trans will be a Jerico dr4, when I save enough money.
