It is indeed an interesting thread, however in my case I just felt that
there was not enough contact at all and also this particular
implementation was done on the cheap, rather badly. In fact there was
about 5 fingers at each of the fixing positions for the socket, many of
which had broken off. I felt that this was not an ideal situation and so
decided to remedy it. I mistakenly thought that the SK-1900 was in fact
a socket with a grid collet but have since found out that this is not
the case.
A picture speaks a thousand words so have a look at this:

Notice the sputter marks, apparently the blower failed and no one noticed!
