What happend to 320K resistors ?

and whats the flex resistance of a 1206?? stiff as a man dead 2 weeks. all people keep pushing is vibration resistance and inductance, try failure mode, inspection, repair, flex,

and you can use heat sink clips nice on through holes to HIGH effect and have easy probing with the most basic of grabbers without a lab setup. you can hook on to them upside down in a panel with a flash light on your head if you wanted to while your being held upside down on a rope no problem.

This does strike me as a bit strange. I still use them for prototyping occasionally, and might consider it for a kit aimed at total beginners but otherwise there are few reasons to use small through hole resistors. There's always the huge chunky 1206 surface mount parts for people that have poor eyesight or shaky hands.

Who sane uses 1206 other than for parts which must be large? Even 0805 is too large for most passives.

coppercone2:
1/4 watt

you want a 1/4 watt smd you get 1210 minimum , depending on what your customers believe

1206 is 1/8 my bad

You can buy 0.3W in 0805. In 1206 you can get up to 1W.  And you don't need 1/4W in 99% of cases, 1/16W or 1/8W is more than enough usually. Just because small TH resistors usually come with 1/4W rating does not mean you actually need it.
