I think the less holes result from the numbers of expansions we play with. We play 2 basic games, 1st and 2nd Ex., Family (red heraldics) and the lake (60 tiles). There are not so many possibilities for tiles to not match to other if there are only "farm, way, town, water". And many water-tiles have only farm and water edges. But I produced another 20 lake tiles (end-tiles) to get less holes than now, and we will test the next days... If playing with more expansions ... you know
The limitations of the playing surface was only a small problem, we sometimes continued a city or a way on an other place so that there were no limitations in justice...

We play the lake with the following rules:
3 points per tile, 3 points per delphin (like heraldics in a lake), lake with only 2 tiles counts 3, lake with only 2 tiles and ONE delphin counts 4, lake with only 2 tiles and TWO delphins counts 5. Final scoring (unfinished) 1 point for every tile and every delphin. Builder in a lake is possible...
We also play it that way with the towns (I think there are 2 different ways to count some people count 2 points per tile even a town only is made of 2 tiles), we count: Town with only 2 tiles counts 2 (1 for every tile), every heraldic in that 2-tile-town counts +1.
