I’m up for that. Backinamo is a busy forum and the Bandit videos each get over 1000 views. So I think a year-end poll would get plenty of votes 
In early December in the current year, readers would put forward their favourite 3 slots of the year. Use your judgement e.g. Bandit Sunday slots and other channels to check the slots’ debut year is from the current year. The Bandit or Seedy would then populate all of the reader slots, taking out duplicates, into a single list. These are the shortlisted slots.
In late December, every reader would cast 1 vote on their most favourite slot. Then like in an election, the votes are counted and arranged into a top 10 or top 25 depending on how big the poll becomes.
That’s only my suggestion though. I think other people should suggest their own system, discuss, and see which one appeals to the most.
Another system that I can think of is what the Bandit did with the White Rabbit competition. So put the slots into pairs and a voting round kicks off for each paring. The slot from each paring that gets the less votes are knocked out and the other slot goes through to the next round. And so on.
