My apologies if any of these have been posted. These are the best I've got:
Meterless Midscreens:
J1/2>2,1>DF1>J1/2>2,1,1+2>Dash>U+4>BF4 - 43% (moderate difficulty online)
J1/2>2,1>DF1>J1/2>2,1,1+2>Dash>Dash>2,1,1+2>J3/4>D+4 - 41% (moderate/high difficulty online)
J1/2>2,1>DF1>J1/2>2,1,1+2>Dash>F+1,4 - 38% (easy online)
J1/2>3,4>Dash>B+2,4 - 27% (hits overhead, easy online)
J1/2>3,4>Dash>B+2>BF4 - 27% (variant, gives better recovery/positioning)
J1/2>B+3,2>F+1,4 - 27% (hits low, moderate difficulty online)
J1/2>B+3,2>F+1>BF4 - 23% (variant, gives better recovery/positioning)
J1/2>3,3,2>BF4 - 24% (hits low, easy online)
Midscreen X-Rays:
J1/2>2,1>DF1>J1/2>2,1,1+2>F+J>X-Ray - 52% (fairly easy online)
J1/2>2,1>DF1>J1/2>B+3,2>X-Ray - 48% (easy online)
Meterless Corners:
J1/2>2,1>DF1>J1/2>2,1,1+2>Back up slightly>2,1,1+2>3,4>3,3>BF4 - 48% (moderate/high difficulty online)
J1/2>2,1>DF1>J1/2>2,1,1+2>Neutral J1/2>4>3,4>3,3>BF4 - 47% (moderate/high difficulty online)
J1/2>2,1>DF1>J1/2>3,4>3,4>3,4>3,3>BF4 - 46% (moderate/high difficulty online)
J1/2>2,1>DF1>J1/2>2,1,1+2>Back up slightly>2,1,1+2>3,3,2>BF4 - 45% (fairly easy online)

Corner X-Rays:
J1/2>2,1>DF1>J1/2>2,1,1+2>Neutral J1/2>B+3,2>X-Ray - 54% (easy online)
J1/2>2,1>DF1>J1/2>2,1,1+2>Neutral J1/2>4>Back J>X-Ray - 53% (moderate/high difficulty online, not really worth it, potentially linkable to B+3,2 after neutral 4 but X-Ray always fails for me)
One corner combo I've been trying but failing to execute... it looks possible, would appreciate it if someone more skilled could check:
J1/2>2,1>DF1>J1/2>2,1,1+2>Back up slightly>2,1,1+2>B+3,2>X-Ray - damage unknown, does it work? Edit: No it does not. Thanks to those who checked.
