I was faced with the same dilemma, had a 157 but didn't think it would be right for me so I took it back for a 154. I have about 9 days on it so far this season and really like it. It rides long for a 154. Rode it with Now Drives and the IPOs set up soft. Definately go with the IPOs. I am weighing in at 160, 5'8".
I like BIG trucks!
