You are such a good directional trader (one of the best I have seen in 20 years), why do you bother with spreads?
I use spreads when I feel that the options are too expensive compared to the expected underlying move and there's a high probability of a 100% loss. Ex. ANET is a +/-10% mover day after earnings. I expected that. I wanted to play a position within the 10% expected move with a risk ratio that was at least 2:1 (at least getting twice as much as I put in). That's where I'll set up trades like the ANET 320/330 call spread. I risk about $3 for a potential return of $10 back, and would have probably received that if the move was to the upside. Lately, there have been a lot earning trades where the expected move is much higher than its recent average, and that's where you want to set up something like a call spread or short iron condor/butterfly.
Otherwise, I just put up straight calls or puts like CMG and UPS. I'll take losses at about 50-75% and lock in profits starting at 150%. The CMG position gained +245% and the UPS position was a loss of -76%. As for win/loss, I'll try to stay at 60/40.
