I haven't made a starter with US-05, but I do rehydrate it for pitching. I have noticed a shorter lag time when doing this (pitching in the low 60's F or lower). I then allow a free rise to mid 60's for fermentation (using a thermowell and digital heating to stay at 66F or so). Even so, with this yeast on some very clean ales, like a cream ale, I can detect some clove that is mildly distracting.
