I have three carbon goosnecks & a resi-neck swivel. The carbon necks rarely get used, in fact only for work above 30ft.
I've used swivels for about 5 years & couldn't work without one.
Be wary of peoples opinions of swivels- as with wagtails, they take time & understanding to be able to use them properly, but, when you do, you'll be flying!
