I like the second kit. One main thing I see is that it has a sprag with it so your second gear can take alot more and will feel alot better.

A stage II kit is auto (shifts on its own when In drive position). If you pull it down in 1st or 2nd it will hold it till you shift it, or should anyway.
A stage III kit I'm pretty sure makes your valve body a manual valve body.
