i have used bitspirit and saw that download speed were better than utorrent or any other torrent client i have seen.. BUT the problem with bitspirit is that lots of data downloaded would dl but would not be counted to actual one. i mean lots of data was wasted. i did not get suitable response to my query at the bitspirit forum. I downloaded a around 900mb but actual data was 162mb.. so there are lots wasted data that happens with bitspirit.
Downloads stuck at 17% even after downloading 880mb out of 909mb | BitSpirit
