That seems like a lot of metal.
Makes me very Happy that I run a Baldwin BT839-10 on mine. (with lots of magnets inside)
Yeah! Lots of magnets in the tranny pan, or in/on your spin-on oil filter makes a difference!
So far I can't see the filter media making any difference since wear metals can be as small as
.1 micron up to 15 microns as normal wear! Spin-on filters are OK at particles 20 microns and up!
This PDF has good pics and you may want to up the magnets you use for better effect:
Spin-on tranny filters are similar to the eng oil spin-on filters mentioned: FILTERMAG vs HOMEBREWhttps://app.box.com/s/uxvu8dmscf5wcgftutdm0ejqwgn86tw7
