My biggest gripe with silicone hose is that during large temperature changes the silicone hose will work loose over time and begin to leak. Heavy trucks went to these several years ago and is an issue every fall. (Up here in our area) This is with a t-bolt type clamp and not a worm clamp either. Also, if you do go silicone hose and worm gear clamps, make sure to use a clamp that has a shield or gaurd under the slotted clamping surface other wise it'll cut into the hose over time.
