These are the skill pairings:
Crafting also seems fairly fast, I heard 80kxp/hr, and at a cost of 4gp/xp. This would give me something to spend my money on.
At 94 slayer, I will choose one to get up to at least 95. Probably hunter due to implings.
Runecrafting / Summoning is a very hard pairing, so I don't think I will even attempt that. Mining / Smithing is also a plan for later on, not yet.
