Aprox how much ET can be gained by using a light spool rather than a posi unit ?

In my experience, I usually see the carrier housing crack when using a mini spool. With spools available in the $120 range new, I agree on not using a factory carrier. And if using a mini spool, you would still have to use axle retention, so probably not much difference in price to use a spool.
