If you are not trolling
He isn't strictly trolling, but he is jumping to conclusions as you haven't told us why you're pulling the BB. If it has been in your indoor track iron for a decade and you just want to freshen up the grease, stick with the loose ball Sugino, it's faster than a cartridge BB and will last effectively forever on a track race bike with a modicum of maintenance. If you have fucked the bearings by commuting in all weathers for a month, definitely get a UN55 or a Campag cartridge BB.

No, I thought he was trolling because the Tange Seiki one I linked is the only drop-in replacement (AFAIK) for 75s, it's either that one or Sugino, everything else is not quite right or completely wrong.
As for the why, I will not open it up just yet, but I want to buy the tooling, as I plan to re-grease it before the next winter. Which is also probably an overkill as I generally only ride when it's nice weather (which is most of the time where I live) and avoid rain.
I thought about buying sealed cartridge Tange, but I think it's not needed, I will know more when I pull it out for the first time.

Umm, If you are not trolling, you mean something like this maybe? http://www.retro-gression.com/product/tange-seiki-109mm-iso-sealed-cartridge-bottom-bracket
