IMO the easton posi is very good, but the more power you add on launch, the more chance you'll have to brake it. At what $450 a unit, it could get expensive. Just driving it around town I would say it will last quite a while. With your power adder I would stay 3-series, possible switching to a spool.
what i mean by higher gear is like a 3.55 or 3.42 but they are 3series and dont make a 3 series spool for the 12bolt... the 4.10 i have with the 4series eaton posi does not need to stay... i need atleast a 3.55 for street driving to be fun...
