Cool. I took at the video and the rods look promising.
As a general wondering/suggestion/nice to have....
It would be nice to get several types of rods in a more scientific experiment, recording all the measurements. For example, if you get the original T rod, Merkel rod, current heat-treated T rod, and the Fireball rod (probably looking at the longest - 2 men rod) and put them between two stacks of bricks. You then start putting 20 kgs, 30 kgs, etc on each rod recording precisely how much each rod bends and whether it bends back or stays that way. This way you can precisely show measurement of how much better each rod compared to others in a clear and scientific way!
Also, rod surface/coating tests would be nice. For example, you could set up a test where the rods are severely scratched and have some measure to say they are still playable after a certain amount of scratches.
Without these facts, people tend to discuss vague terms such as a Merkel rod not being bent after 2 years in a bar. This could mean many things. Granted, it generally indicates that Merkels are stronger, but it doesn't indicate by how much. Also people talk about a tougher rod surface, but it isn't backed up by solid facts or experiment results.
The same thing could be done about any component of each table including the table frame itself. In general it would be nice to have a website or study that compared all major ITSF approved tables in an unbiased scientific way in terms of dimensions and quality of each component as well as playability, of course! Just as you read comparisons of computer components on say, tomshardware, before you buy those components, the same could be done for foosball!
Please not that I'm definitely not criticizing or disputing any claims above. But I think many would agree that comparing and discussing facts is much fairer avoiding many arguments and questions. This would make decision making about tables and parts many fold easier.
Heh, if I was located in US I could probably embark on something like that, but as it stands it took me over a year to get an old Brown Marble with all its rods rusted and replaced by stainless steel non-hollow ones.
