The higher he levels gets RS gold faster and faster to the point that at 70 he has already surpassed the miners top speed(provided that he is able to form a strong team) I'm not sure why you don't get that this is a one horse race. The winner should choose a skill that is slower to make things fairer.
Regardless of being fair I think we picked these skills since we both love doing these things. For clarity, we're both members, and my brother is not the owner of the dragon pickaxe. A dragon pickaxe for mining is like a great team to dung. Without it, it's feasible, but it's is much more difficult. The only legitimate way you'll lose is if the opponent is solo and get a D pick.
I was able to find out that Maples price decreased, and flax/bow strings as well. However, since Pking was also released, maples are in high popularity for F2P. My friend suggested I make them, and I made them. In general, I think it's buy OSRS gold the most simple and the fastest. And it will earn you 100k in an hour to just sit here and write and then click back about 15 seconds.
