Sweep or Network ?
I wanted most rounded shape possible..sweep is my favourite tool,i did the joystick handle and the boots with the same technique
i think to be NOT the right person to ask technical Nurbs tips for the following steps:
1-i got limits with English leanguage (i'll start a refreshing English course next week)
2-i have an istinctive approach with Nurbs modeling,started with ACAD 2000 then ACAD 2005,just solids,not surfaces(i remember everytime needed to orient UCS icon..)
istinctive means i got an idea,i do it,trying to find the most simple way ever ! I'm planning what i'll do,but not too much,let follow my" instinct".MOI is the natural tool for this workflow..."a pair of wings to fly "
so:i attach the microphone 3dm file i did,have a try,compare,rebuilt like you want !

------------
I think,without know directely both guys,Burr and Mike have different backgrounds
Burr have a serious approach because he use Nurbs modeling for CNC work
Mike is a graphic designer,then started with 3D Nurbs..so:more fantasy..
i follow Burr's youtube channel and also Mike's website,first one you find correct techniques,second you find techniques applied to the realty
following both guys you can have a complete panorama of MOI
