I would look at their V Drive pendulum model... it's both a pendulum sight and an adjustable sight all in one. They are very well constructed, machined from aluminum with very tight tolerences. The benefit with the V drive is much like that of an open class sight, allowing you to mark yardage increments on a side reference tape and then, without tools, simply spin the actuator rod to make yardage adjustments on the fly. Trophy ridge makes some super nice sights... and at a reasonable price. The 0.19 is what I like, but that is just personal preference. Good shooting to you.
