| I have used the indi bridges and thru tail. That is I am using them on basses I am building. The bridges are pretty solid. Good adjustability, especially the thru tail. The finish leaves a little to be desired, but for the money they appear to be a steal. I say appear, as the 2 basses are not complete, so I don't know what is going to happen once I attach the bridges. I would go for the slim tail of those three, good adjustability and looks better than the contour tail. The spector style fat tail only has height adjustablility, so I would be wary of that on a homemade bass, as I would want the most adjustability as possible. Most basses generally have their intonation in a similar style to how that bridge is set, but some are very different. With the slim tail you will be able to intonate the bass at least.
