Diff Dilemna! Need opinions!

Wheelhop isn't caused by the diff. If you put a spool in, it won't fix that problem.

Everything is an opinion, but mine is that its not worth it to run a spool. There are plenty of differentials that should be able to handle what a street car is going to dish out.

In addition to the hazards DartOS mentioned, the lack of slip puts a ton load on everything in the axle.

Try and push a spool car with the wheels turned even a little bit sometime.
