Here's my drill for a Legacy:

Enter at least a 1 mile initial.  If I am at an unconrolled field, I call at least one minute before and when at 1 mile on initial.  It is my responsibility to fit into the pattern so I don't expect anyone else to have to do anything based on what I am doing.  If that won't work, I break off the approach and enter conventionally.  If there is another a/c in the pattern I will announce whether I will break and land in front of him or enter downwind behind him.  At a tower field, the tower may give you the altitude for initial (which may be higher than pattern altitude) and will tell you to break right or left and where to do it.

Absent traffic conflicts or contrary instructions, I come in faster than cruise and break left at the numbers.  Power back, not all the way to idle but fairly close, speed brakes out and 60 degrees of bank.  Ten degrees of flaps at 170 kts.  Brakes in at some point depending on progress.  Gear down at gear speed and flaps full down.  Aggressive back trim during all of this process, which usually gets done just past the 180.  At that point, I reduce power to idle and adjust the turn to land without touching the power.  Works well if I don't mess it up.  If I have to break past the numbers, there will be a mini-downwind leg and there is more time to get set up for landing.  It may also be necessary to carry power for a while.
