I do not like 38 for some personal reason -- my favourite writer, Ekzepuri (I am not sure how to spell his name, read him only in Russian translations) was killed in the 38. That is why I flied it in AH only couple of times, and unlikly that will fly often.
But if you want some advices from someone who fighted against it, then:
1) Better wait, till it will be modelled right. Many bird in AH were remodeled after implementation. Normally it takes couple of patches/releases.
2) Boom and zoom.
3) Watch your e, do not bleed it too much.
4) If in a bad situation -- run away, your speed let you that, so use it.
5) Use your perfect climb rate when possible, staying higher is your best chance against other fighters.
Hope, that helps,
Fariz
