I purchased my cluster when doing the highline upgrade with the white leds already changed, it wasnt advertised as white so i was surprised when it lit up!!
Since then i have had a practise with a spare cluster (thanks joegti er sorry R32) and it is fiddly but quite doable, but i have had some experience in soldering before as im an electrician by trade.
To be honest i never really look at the rev counter either and rarely look at the speedo as the sat nav chirps away if i come across any speed cameras until i slow down!
Not that i get to drive the car much the missus has it all week and i get stuck with my van...until the weekend.
