I've no direct experience of the Lunt front mounted 100mm etalons but my Solarscope SF-100 is heavy enough (around 5 lbs for a single stack unit) to have a significant effect on the tube balance, though easily countered by sliding the tube to a different position on the dovetail & moving the counterweight a bit further down the Dec shaft. The weight distribution also makes the mount's job much harder, damping time for vibrations can be increased unless the mount is specified for a much heavier load than that actually used.
It's certainly something to take into consideration.
