I can understand what your saying ,but we've held joint (three counties) selection /championship shoots and had much bigger /better shoots (people turned out because the shoots were bigger + the usual inter county rivalry) and decided to split the money equally and all counties ended up with more levies than on a normal championship /selection shoot , although some said they thought each county should only take levies from their own county shooters ,and levies from shooters not in any of the three counties that were holding the shoots split equally . i dont think trap boys have major issues (not a trap shooter myself) i think there just happens to be a lot ,lot more sporting shooters than trap and other disciplines. especially when you consider sporting is sporting , whereas in trap shooting there are , DT ,UT, ABT ,DTL,DR, OT AND HELICE SHOOTERS and many( which is their choice ) to shoot their particular version of trap.The down side is that with multiple counties holding a joint shoot then the levy is divided between them. So four counties with a £2 levy, 100 entries equals £50 for each county. A quarter of what they would have had with a sole championship. As a general rule I think sporting is fine and has few problems. You trap boys need to get your act together and sort it out as you clearly have major issues to tackle.
There will always be disciplines that will not be as well supported as others ,but that does not mean they have problems or they're worse disciplines than the others it just means more people prefer a different discipline . i.e... I prefer Larger (Kronenbourg ) you might prefer Bishops Finger, its just a choice !!
