i have got 61 range 60 def etc etc and i was wondering as i am nowing using the rune crossbow what setup of armour should i use and where should i start training now ???

Bandos d'hide, rune crossbow, Fury if you can afford it if not glory works, archer ring if not recoil, and I mean for that level thats pretty much the best setup i can think of unless your rich and go full ranger boots, tunic and all that

Depends on the budget, if you have extra gold to spend then this would be an ideal setup.

Full red dhide

Archer's helmet

Glory/fury

Ranger boots/climbers/or snakeskin

Red dhide vambs/barrows gloves

Unholy Book/ Rune kite shield

Any type of throwing knife/ Bone C'bow

 

And i'd recommend training at sand crabs until about 70, or keep it classic and kill blue dragons or any dragon you prefer.
