Theory craft: Best 4 songs to twist at 51 as a melee solo twink bard?

[Diabolic2442]

Yes, please don't tell me how awful bard melee solo is compared to charming/swarming/grouping/etc. I know but want to take this specific path in the game until it becomes too painful.

Now that it's out of the way, my bard is fairly well twinked with SBOZ/BOC/Seahorse 34% haste belt and Lute of the Howler(40% spell haste).

I'm thinking the best 4 songs to twist at 51 would be: Longo's for slow, chant of battle for stats, hymn of restoration for regen and Jonathan's provocation for haste. However I realized that Werewolf form is spell haste and it isn't stacking with Jonathan's which is 8% more. Few questions I have:

1. Is it worth twisting Jonathan's provocation or should I switch to something else that would be more beneficial than 8% extra haste?

2. What twink item should I spend my dkp on that would be a huge benefit to continue melee solo 51-60. Epic? Tunare/Koi Dagger? 41% item haste? Although I read piercing is lower than 1h/1hb so not sure if Tunare/Koi dagger is worth it.

3. Anyone have other recommendations on what would assist my journey of melee bard solo to 60?
