Runner Runner Flush

[Mercman572]

Table is very loose. PFR'er has been stacked and has been raising most pots preflop since. He's been multiway just about every time he's done this. So I expect to have this multiway in position with my call preflop. The river raisor is a calling station (45/6/.85/30). The blind will bet any piece of the board here.

Blind has called me down twice with mid pair when I fired 3 times, so I could be making a $25 call in a potentially $75 pot. However, UTF's aggr. has me worried. There aren't many other smaller flushes possible given the last 3 cards, could this be a str8, 2 pair, or lower flush enough times to make this call?
