Best bones to buy for price vs xp ratio

[rangeroncrak]

title says it all. What would you recommend as the most cost effective bones to buy for training prayer?

I personally never buy bones but I heard this woman in COE who sold her d bones to get big bones since it's way cheaper xp.
Agreed: you have to do more runs to your guilded altar, but it will be lots cheaper
