Another solid vote for the Werner Powerhouse. I absolutely love my 197 straight shaft.....
That said, here is an option I am willing to bet most of you are unfamiliar with.
Z & J Sports out of China. Had a friend order their "Fancy" fiberglass/carbon in a 197 and it has served him well. We have made extensive comparisons to the Powerhouse and they are almost identical except the Fancy has slightly more surface area on the blades (very slight), and that the Fancy ships in multiple pieces and must be assembled and sealed.
