Im a bit the same as you - dont like complication too much. Ive got the same combo you have and I find the way I do it, gets pretty good results.
I dose into the basket just about to the top, then give it a couple of medium taps on the Mazzers forks and then do a little more dosing until its just over the top, or appearing that theres enough coffee in the basket to fill it up.
I then take the portafilter away and swipe the placky spoon handle across the top to level things out, making sure that I fill in all the spare space in the basket, so there are no gaps.
I then tamp it, give it a tap on the tamper and do a spin for the loose bits, load it and then pull the shot.
Hope thats some help, but unfortunately I think there are so many ways to do things, that there could be another 50 or so methods that would work as well.
Good luck and remember "keep it simple stupid"
