It took me three years to figure it out, but for split files, mainly two RS links, always go for part two first. 90% of the time the two files are not equal in size and the second is almost always smaller.
Get the smaller file first and you won't have to wait so long to get the main file.
Maybe it was obvious to some, but if it took me - a well seasoned pirate - so long to realize than this small tip will most likely help SOMEONE
