Amps that have vacuum relays typically work fine with 8 msec. I don't 
know the 418, but the Titan 425 and the Herc II both use vacuum relays, 
and work fine with 8 msec. The shortcoming of this is if you work CW 
faster than about 30 wpm, the elements are shortened too much. AND, if 
you work a LOT of CW in full QSK mode (like contesting), those vacuum 
relays wear out in a year or two. Ask me how I know. :) This is NOT an 
issue for casual operation.
