MEP or TYX, page-8

TYX is better than KCN - but comparing TYX with MEP is apples and oranges until TYX are able to stump up a Prominent Hill. MEP have proven history - they have the right team of Geologists to put the money in the right area. They are frugal with their funds and because of this many companies partner with them and fund them.
Even with all of that on their side you still need to have some luck to hit the jackpot (either team). I will still be backing MEP over TYX - but either way if either of them find another prominent hill there will be a small open window to get in before they take off (usually)..
