a welcome dilemma at 8/b - how to play a rut

[imported_getfunky]

Should I have raised on 5th street? I was torn because my position was poor for building a pot. But I had luckily caught a baby so I might trick the ace and didn't want any back door lows, weird straights or miracle trips to beat me cheaply. Was that too tight a raise? Should I have waited for 6th steet before raising, trying to keep this a multiway pot? Thanks in advance:
