The things you mention are not file types. They are the (alledged) speeds of the hosts sharing the files. It will probably make no difference to you who you download from in speed terms, as even of they are very fast, your download speed will still be relatively slow. My advise is to not go for T3 files for a variety of reasons. My last attempt was yesterday and the file was "corrupt". In this case I deleted it with further ado .... I digress....

The size of a file, which is governed by the bit rate, is more important for you and you must decide whether you want high quality ...192 bit rate or higher, or pretty good 128 bit rate which will download faster.

Let us know if this helps.
