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.
