The Key To Open Any Door Tournament

Right, Im working on a similar line to Here I Go Again, where Im keeping things nice and simple, however like Here I Go Again, the numbers are going up.

What I need is for 16 people to enter 2 vapourbots each, on a first-come first served basis, which will give 32 machines in total. There are seeds of:
1 - Frank
2 - Paul
3 - Martyn
4 - Kody

So if those people enter, can they select one of their 2 machines to be the seed.

I think I have covered everything, 100KG limit for tracks.

BTW, there will be a prize for the first person to guess the link between the names of my last tournament and this one
