ICue questions- Do they work equally well with different beam spreads (26,36, etc.), or best with certain one(s)? Do they work well with old Altman 360's as well as S4's? Can they do some quick spin effects, or more just used to re-position as different fixed specials? I am thinking of using one or two in next show as re-positionable FOH specials, but would also like to use them to spin (while lit) into audience for couple scenes where actors run off stage and exit back of house. Is this feasible? When using to light on stage, will there be too much fixture glare to audience, or are there certain tricks to aiming these things to avoid this issue? Last, any experience or thoughts using with extender arm and color scroller? Advice and experience appreciated. Thanks.
