I have been agonizing over several different regulators as I prepare to make a purchase. Getting back into diving after a 25 year hiatus. Anyone there have experience with both the S550 and D400? Scubapro claims that the D400 has better bubble dispersion, true? Do they breath about the same at all depths? Reliability the same? And to throw a wrench into the works, I am attracted to the Dacor Viper Tec. Fits best in my mouth and of course has good bubble dispersion as a side breather. This process is like buying a car without getting to test drive it first...crazy! Thanks...Bob
