To a couple of your points:
IMO, both the HT and MN are a problem. Both, IMO , have strayed from what they were established for.
If a person never runs or trains his/her dog they are not participating, they are spectators watching someone run and train their dog.
The guy/gal who finds time to train and run their animal is usually the same person throwing the flyer at the test so someone else can watch there handler run their dog.
As to the club and what it offers: we will celebrate 30 years as a club this year. We were formed at the beginning and did so to allow retriever lovers a chance to train and test there dogs in this great new sport. We hold 2 HT's each year so our members can run close to home and enjoy our sport together as club members. We do not limit as we have ample grounds and a dedicated membership. We are lucky. Many clubs do not have the ability to hold unlimited events and as such, members should not be penalized by not being able to enter the event they are hosting. If that trend were to continue it will cause people to reflect on why they are members of a club to begin with.
None of these post are anti pro handler specific: All are looking for a system where everyone has a fair chance at entering any given event.
But then again, I suppose I could be mistaken and there is not problem.
