Up. I am daring to speak from ignorance (I have yet to make a single FT8
QSO) but will ask anyway whether this is a "good idea."

Your post indicates ignorance of how modes like FT8 work. I suggest that you install WSJT-X and make some QSOs before making rash statements like this based on hearsay. It might interest you to know that some first rate contesters and DXers are active using FT8. I use it extensively on 6M. One of those promoting FT8 for contesting is W0YK. FT8 is close to replacing RTTY for DXpeditions. Top CW ops like AA7A, AA7JV, and K6MM were among those who did a lot of FT8 from KH1, and more top CW ops did the same from VP6D. AA7JV appreciated the ability of FT8 to put EU stations in the log at signal levels 10 dB below where CW works.

Modern contesting makes extensive use of computer software and hardware. I have yet to meet anyone who can copy RTTY in their head or generate by hand. All the CW that most of us send in a contest is computer generated. The computer checks for dupes, presents us with a list of calls to choose from when we start to enter one. The computer puts the calls it sees from its RTTY decoder into a stack, from which we can automatically work the one at the top. We can initiate a QSO by clicking on a call on the screen. CW and RTTY skimmers fill our bandmaps with calls, highlighted by color to tell us whether they're workable and their multiplier value. In contests like CQWW, the computer fills in the exchange -- all the human does is copy the call.

I am among the many OTs who started contesting in the '50s with a bug, two ears, paper logs and paper dupe sheets. I wonder if any of those purists who look down on modes like FT8 still do that.
