I use 1/2" silicone for everything (except I use reinforced vinyl on hoses connected to the plumbing), and I have experienced everything from virtually no external resistance, to 100% (stuck sparge, closed valves), and have never experienced anything like this, nor have I ever heard about it from countless other people using pumps and silicone tubing.
I would normally not even bother pointing it out, but at $2/foot, even regular silicone tubing is fairly expensive. I also use a plate chiller and an in-line filter/hopback, and so I have about $60 of hose (30 feet) JUST for use on brewday (I also use 1/2" silicone for racking), which is not exactly a negligible cost, especially when you add the cost of quick disconnect fittings. Still, $2/foot is peanuts compared to the $7/foot for the braid-reinforced stuff... that's over $200 just for silicone hose, and I still have more to add. Ridiculous... I could put that extra $150 to very good use.
Besides, if you are getting enough resistance on your line that a hose collapses, from a closed valve, stuck or near-stuck sparge, or whatever (though I still have never had a problem, with both a March 809 AND 815 even on full-throttle), then it is a problem you are going to have to fix regardless of what kind of hose you are using. So really, it's just a huge waste of money - though I DO plan to eventually get a length of braided silicone to replace the braided vinyl I connect to my water supply - for the opposite reason though, as regular silicone tubing will easily burst from the pressure of the water supply.
