I have Nylgut Minstrel strings and calfskin heads on my 2 banjos - one tackhead, one tensioning. Because I play in a 4 piece ensemble, I drive the strings pretty hard to keep the volume up. I also get the heads as tight as possible before the performance by heating them with a light bulb clamped to my stand. This works for the first set, but the head inevitably loosens, the bridge sinks and it sounds like I'm slapping the neck with the strings. Other than constantly heating the head to keep it tight (which is not always practical or possible), do you have any other recommendations? The bridge is 3/4" high, so I don't think a taller bridge will be a solution...
