Are there disadvantages of heat shrink tubing with higher shrink ratios? Heat shrink tubing comes in various shrink ratios. The most common of which is 2:1, but there are also 3:1, 4:1 and higher. Assuming cost is the same, are there any disadvantages or consideration points when using higher ratios? $begingroup$ "assuming the cost is the same" I wish it was $endgroup$ – Mark Omo Sep 11 '18 at 16:10 1 Answer 1 One small disadvantage I've found is that the wall of a high shrink ratio tube can get quite thick when shrunk. If your joint has some small diameter sections then the high ratio tube might shrink all the way, conforming tightly to the wire, and become quite stiff compared to a 2:1 tube. There's also a problem of asymmetry. If the shrink-er doesn't use an air deflector or turn the joint while heating it, one side of the tube will shrink first, making it asymmetrical. A 2:1 tube suffers less from this as it can't go so wrong. $begi...

19 1 Usually I find a flight I like that uses one or more connections with the same or different companies. In these cases, if the distance between the first and the second connection is not too large, I prefer to go by bus or train and then take the flight. The problem is that sometimes it is more expensive to take the flight in the second airport than to take the flight from the first one. I mean, I'm wondering why sometimes it is more expensive to take only a flight than to take the same flight and another one. A practical example (and real, you can check with SkyScanner). Imagine I am in Madrid (Spain) and would like to go to Rio de Janeiro (Brazil) on April 1st. The cheapest flight I have found is this: TAM airlines: MAD -> GRU -> GIG : 507 € Fantastic! GRU is one of São Paulo's airports. That's perfect for me! I'll go on to Rio traveling overland. But then, I look for this flight (MAD -> GRU, non-stop): TAM airlines: MAD -> GRU : 597 ...
