Using Thundernews and Altbinz always get results, difference between Nzb's and torrents is that they are linear downloads whereas torrents depend on how many people are sharing and they are non linear so you might get the 56th % first and all the others in a random order. Used to max out my 20 meg line with Sly but after moving am on Plusnet which is the worst connection I've ever had and only getting 1.5 Meg download maximum.
