Check the AT853 mic outer diameter v. the Shure A81WS or DPA UA0896 inner diameter slots - I think you'll find the mics are far smaller than the inner diameter slots in the windscreens and would prove too loosy goosy to effectively stay put. 'Course, AT853 + small screen + Shure/DPA might do the trick, but I've not tried it so have no idea if it'll work. Check the Archive | Mic Setup forum for a thread on windscreens with a link to one possible source for w/s that may fit - Olsen Audio, if memory serves.
