If you have to buy a BB that's not the exact size you want, you always buy the next step up. So for your case, it'd be the 111.
Yeah, except a 108 may give you a more correct chainline. Often spec'd sizes are fudged up a mm anyway, if you add another couple mm on top, it starts to become significant. In practice, it doesn't really matter than much if your chainline isn't a perfect 44.5, but it's nice if it is.
Obviously if the chainrings hit the chainstay, than nothing works, so I understand why people suggest playing it safe.
FWIW a 108 Phil BB is the correct size for a modern Sugino Mighty tour crank on BSC shell. Not sure about old Suntour Superbe.
Tange and others make a cartridge BB that is much cheaper than a Phil.
