None of your statements are true.LOL at your use of NHLe.
Slovakia has two proven NHL forwards in their prime, to Latvia’s zero. I comfortably take Slovakia’s top 6 over Latvia’s, and I think most neutral fans would as well. If these teams somehow meet, Slovakia will be a clear favourite on paper.
The Slovakian forwards are not in their prime. Forwards peak at 21-25 yo.
You wanted to say they have established themselves. They're in their prime commercially. Biomechanically it's Balcers and Blueger who are at the best years of their career.
It doesn't matter whatsoever what you or anyone else would take.
Slovakia would not in any way be clear favorites in a match up against Latvia.
