Using so-called "controlled PTT" on CW may be a reasonable compromise 
between full QSK and semi-BK-in.  I'm not a contester, but I see many ops 
using either a computer card or other type of computer interface that will 
automatically control the PTT cycle when using a keyboard - not sure it's 
possible when using a keyer as it may require a typing ahead.  Anyway, a 
solution does exist that will prevent excessive T/R relay activations while 
not having to wait from T=>R at the end of a transmission.
