Combat Neck Dagger

Here are my stats:
Attack: 60
Strength: 57
Defence: 60
Prayer: 28
Hitpoints: 59
Total Combat Level: 71

Here is what I am using:
Head: Dragon Med Helm
Body: Granite Body
Legs: Rune Platelegs
Boots: Dragon Boots
Shield: Toktz-Ket-Xil (Obsidian Shield)
Sword: Dragon Longsword and Dragon Dagger (P++)
Ring: Ring of Dueling (7)
Gloves: Safety Gloves
Cape: Obsidian Cape
Neck: Amulet of Glory

Now I was thinking about still training at the rock crabs, but im not sure if thats best for me anymore.
I dont want to train anywhere dangerous like the wild or somewhere like that.
Training in a safe place where my player cannot get attacked by anthing else that could kill me is where I am most likely spotted to train.

And also, is there anything specific that I should buy for training
For example: Potions, Food, etc.

Thanks.
