My band went to an open mic night last night. The venue supplied amps, PA sys. and mic'ed drums with overstuffed 20" kick and double Pearl pedals. The Taye drums were tuned to cardboard, stiff as a table-top and difficult to play. I couldn't make out the brand of heads but can most coated heads be tuned that way and not warp the hoops or can the thickest heads tuned that way?(I'd be afraid to tune mine like those.)
