Yeah, I don't really see the benefit of that handle hole either, but the sticky pads are good.
The LR32 is definitely the way to go there. It was suggested to me, when I got my first TS, with the quote "even if you don't see the need for it now" "Some day you might and it doesn't hurt anything if you never do."
They are the same cost, here in the US anyway. I did learn here on the forum, that it is not the same in Europe. It does seem funny that they would do that extra machining step for free though?
It was less than a year, when I got the rest of the LR32 parts.
