I play in the Chilterns League and certainly from my personal viewpoint it would be a good move for my club. For reasons unknown to me, it was before I joined, we declined an invitation to the TVL and as a result we are arguably playing a lower standard than we are capable of. The same can certainly be said of at least a handful of clubs in division 1, standard wise, and quite possibly one club in their 2nd season in the league currently smashing everything in sight in division 2.
The one good thing we have currently in the Chilterns League is that the travel time is short and it compares favourably to when I was playing in the TVL - I didn't really enjoy going from Theale to Teddington or Kew for a game of cricket! I'm sure they shared the same feelings too. From what I've heard on the grapevine apparently quite a few people are against it in the Chilterns League but I am unsure whether that is the players or the various old non-playing blokes sitting on committees at the clubs and the league.
One of the arguments I saw against this proposal from some TVL clubs was about the standard of grounds some of the bigger clubs might have to play on. Whilst I understand their concern regarding this, there are some 'big' clubs who have awful grounds in the TVL - off the top of my head Stoke Green and Kew spring to mind. This was also the argument trotted out when the Kent League decided to stop being a closed shop and expanded many years ago. The original 18 clubs, I think it was 18 anyway, were against expansion as they might have to play on some awful grounds. I'm pretty sure if you were to ask those clubs now whether they think the expansion was good for cricket in the area then they would probably think it was.
I am also questioning whether it would actually increase player participation or not. My initial reaction was no, then I thought that it might do but perhaps only at the lower XIs as the players generally playing a higher standard already will travel to play.
I stumbled across the following in the local rag earlier:
