Monk & Cleric/Shaman Duo

[MaSQue]

Sorry, this will be long.
Hoping I can get constructive help on this one guys.

I originally leveled my Shaman to 41 a while back and quit the game for a time, recently returning with a friend and he fired a new Monk up so I did a Cleric with him and we have done the Duo thing from 1 to 41. Now I understand how god mode a Shaman/Monk is but I have some questions. The Monk/Cleric duo has actually worked out really well, never had any serious issues maintaining Mana and keeping buffs on the Monk. The Shaman on the other hand it seems like I am constantly having Mana issues with keeping the Monk fully buffed and maintaining Regen and Haste on the Monk as well while all the while keeping him healed with my crappy heals (compared to my Cleric).

The Cleric needs to maintain 3 core buffs and has great heals along with Rezz spells as I level they get better while the Shaman has like 8 core buffs plus Regen and haste and it just eats my mana up and I am finding it hard for him to keep constant pulls coming and have the mana to keep him alive with the Shaman where with the Cleric it is quite easy. Before it was easier due to I had a loner Manastone and a Fungi (Both loaned out to me which I no longer have) so before it was simple, just constant Mana Stone my Mana back up but Cani isnt no where close to Mana Stone lol. "Both the Cleric and the Shaman have high Wisdom and Mana Pools btw"

The Shaman and Cleric are both 41 now and we plan to continue on to 60 but we are not sure which will be better. As I said, we have had zero problems with the Cleric and Monk duo and I am wondering if I should just stay with the Cleric and keep on the journey to 60 as we currently are. Gongshow swears up and down Shaman is the way to go and I long ago learned to listen to my good friend, but I am not sure why, but I just feel better with the Cleric in the Duo. I feel comfortable with the Cleric even though the Shaman has SOOOOOOOOOOOO much more utility on a PvP server. End game though Clerics in groups are sick plus the Rezz's are going to come in handy with death's.

I could really use some help on this one guys. I understand the Red99 forums are the Devils work lol but I can't decide on this on my own and am hoping I can get some constructive thinking on this one.
