Personaly i prefer feed on,but do not object to shotgun.
In the winter league if you turn up early and are second in que ,there is nothing stopping you from leap frogging them.
When i say leap frogging,i don't mean putting your hands on there head and jumpping over them
The only problem i see with shotgun start's,is not every one uses the internet to see if they have to book.
I know that it's fair for everyone to get a couple of clean target's to learn from,but it's also nice to stand in the que and catch up with other shooter's.
