Figured i'd try my hand at the sum puzzle after having burnt out, so have an afternoon's effort. 

New Solution 1 was a 325G/90C 1/2P6 solve clocking in at 631 Sum4: I made that cheap and slow for a 185G/150C 24R, and finally this. 

This feels a little on the pricey end of a sum solve: I wonder if sub-500 Sum4 is possible.
