Thank you very much.

if you already got some good results,
just use the the same procedure, tweak & scale,
you can always try new different stuff like different niches, building your pbn, cloacking, tiered links,
if you're tight in budget, just stick with high quality stuff at 1st, it does have a much better chance of giving better results
