I'm going for Waterford again, 1/2 (Will Hill) away to Salthill Devon on Saturday. The record of each team is the inverse of the other, with W'ford having won 3 out of 3, scored 6, conceded 0, and Salthill lost 3, scored none and conceded 6.
Price isn't great but it's the most solid thing going this weekend.
Depending on prices, I might also look at laying a currently-awful Shamrock Rovers.
