In all seriousness the 38 is a tremendous plane and has many die hard advocates who gladly will share what they know with anyone who demonstrates a significant interest.
The 38 has a pretty steep learning curve and I'm far from qualified to comment beyond a few basics...
1) When in doubt take the fight up. The 38 does very well in the verticals and zooms and spiral climbs are your friend
2) Do the Jenny Craig, the 38 is all about getting "skinny" when you need to. Once you learn to control the profile you present your halfway home
3) flap like a bird, sting like a bee. The 38 requires prudent and frequent flap use and the center mounted grouping lets you reach out and tag folks.
4) Throttle and Rudder are important in all planes but the 38 excels in the "sweet spot" like few others. Managing speed and using your rudder makes the bird dance
This is a recent clip I already posted since its a "no icon" fight from AvA but it gives you some idea about the 38...
