What type of bone would be the most efficient to use on a gilded altar with prayer brawling gloves. With the 1.5 times exp im not sure which one would end up saving me more cash in the long run.

try this equation:

 

price of 1 bone divided by exp from 1bone on guilded atler to find the gp/exp rate

Always use the highest bone possible (Frost dragon bone at this point). Saves you money in the long run ;)

They last for 1275 bones. I'm going to assume that, if you didn't have brawlers, that you would be using dragon bones.

 

Now, the different bones per brawler:

Dragon bones: 481,950 XP, -7,058,400

Fayrg bones: 562,275 XP, -8,398,425 GP

Raurg bones: 642,600 XP, -10,752,075 GP

Dagannoth bones: 836,718 XP, 15,300,000 GP

Ourg bones: 937,125 XP, -18,997,500

Frost bones: 1,204,875 XP, -22,185,000 GP

 

Now, just the savings per brawler over using dragon bones, no brawlers:

Dragon bones: 3,529,200

Fayrg bones: 3,953,775

Raurg bones: 3,364,725

Dagannoth bones: 3,081,233

Ourg bones: 1,589,500

Frost bones: 4,284,000

 

So you should use frost bones. Plus they'll save you the most amount of time, and are buyable near min atm.

Always use the highest bone possible (Frost dragon bone at this point). Saves you money in the long run ;)

this. With brawlers there 17.4 gp/xp which is cheaper then dragon bones without brawlers.

Right now, at the current prices(16,5k frost 5,5k dragon bone), assuming you have one pair of brawlers to get the same amount of experience with either type of bone, assuming 1275 bones per brawler and per hour, you'd have to value your time at minus 780k an hour to be more efficient to use dragon bones. So yeah, use the best bones, and as an added tip, frost bones are really low right now, but are bound to bounce up very soon.

Ok, thanks for all the fast replies. Now i just have to use 3 pairs of these =D
