I am wondering which scene tracker (such as scc, tl, dh, fl, ipt, tl) has the fastest initial download speed. By this I mean when they first get a file from a topsite and they are the only ones seeding it before other seeders hop on board. Currently I am on theGFT and AR. Both of them get scene releases quite fast, but both of them seem to be limited to around 3 mb/s initial download speed (slightly older torrents can be much faster, as in 10 or 15 mb/s). Are there any scene trackers that can give me these speeds from the get-go?

Thanks
