Also, in addition to Scoble's advice - take your old ultegra spacers and lockring (provided it's the same small cog) and use them in the 105 cassette.
All of a sudden you have a 105 cassette that is very close to ultegra weight.
The other difference is the finish, 105 looks shiny and ultegs has a shot finish.
Ultegra vs 105 11 speed cassette
Any difference in shifting? Which lasts longer?
