Bard Song Twists/Stacking

[Drakanor]

Hello all, I am interested to see if anyone could tell me essentially what are the best songs to twist in the following scenarios (pve) for a lvl 60 bard with access to all spells:

HASTE

-1) Best haste twist while solo

-2) Best haste twist while in a group

-3) Which haste song (if any) can you twist in a party that has ench haste

HEALING

-4) Best twist for HP only regen in a group (medding non-combat)
-5) Best twist for hp/mana regen while in a group (medding non-combat)
-6) Any stacking isuues with Regen/Chloro buffs?

I have searched the forums/wiki as well as other sources to find answers, and acknowledge a wealth of information available. However, answers to these specific questions will be much appreciated, and I'm sure useful to any new bard besides myself. Thanks.
