OK, here are a few questions.
There has been a lot of talk about Corrosion and cracking, re. Aluminum and Acrylic specifically. I would be curious to see if we could get responses like the one D-Tek gave a bit ago regarding these issues.
However, I know of corrosion issues on one commercial block only. That is the Silverprop Cyclone 5, which was humorously enough explicitly not waranteed against corrosion unless it caused an actual leak within 6 months. Likewise, the only cracking I have heard of on a professional block was on a DD maze 3 (and only one at that).
Also, with commercial blocks, Aesthetics are often a major concern, I would be curious to know what the priorities were with manufacturers, re. their blocks.
Additionally, most commercial blocks are (to my knowledge, especially with the big companies) released after significant amounts of testing. What flow rates, tubing diameters, and the like did these companies optimize their blocks for?
Finally, I think we should address warrantee issues. Some blocks, again the Silverprop, come with a warantee that makes me wonder if the manufacturer has any confidence in the quality of their product. Finding precise warantee information is often not easy. I think that addressing that issue should give an effective feel for how much confidence a manufacturer has in their own product.
