I have both robline and salsa on my cat
robline feels softer and nicer, salsa has a slight plastic feel to it.
the main drawback to salsa (as Catman mentioned) is it's colors are limited and you don't want multiple lines onboard with the same color/ look (see images for the 2 choices) ... to easy to confuse them
It appears that the committee is pretty equally divided between Salsa and Robline with one strong argument for Maswli. While I'm deciding can I interest anyone in about 65ft of red sta-set?
