The PT-6 is fine. It's not great, it's not bad. The effort is minimial, the cost, well, that's up to you. The end result, yes, I like the VPI arm better. I didn't fill the holes, as the new ones were clocked almost perfectly between the old holes. I did use some measure (tools and swear words) to flatten out the old holes for a better mating surface. They're not exposed so you can't tell. And a current picture of the Traveler.
