What level's would you recommand for F2P Pure or Hybrid ?

Well the topic says the question so let´s get this started

F2P? I would be either a strength pure, or attack/str pure, or range. Mage is hard due to a lack of income on f2p, and there are enough monsters to support a str or range pure

do wc for money, yews are good money f2p

or, do the wet clay method. (buy tons of dry clay, 14 buckets, go to varrock east bank with 14 buckets and 14 clay. fill at fountain, wet the clay, then bank and repeat, filling the buckets at the fountain) (150k an hour)

At around level 70 strength 70 attack is when it will start getting worth while.

70 isn't that hard to get lol, to be a pure pure stay at 50 attack if you want to. Otherwise yea as Yazackie90 said 70 70 seems about right
