When I played over in England there seemed to be no end of these medium pace bowlers who bowled boring balls on a good length and never tried anything. Occasionally you would get a batsman who had a bit of attacking flair and predicted where they would pitch it every ball and belted them but that was rare. We played 45 over matches and it seemed that keeping runs down was top priority. To be fair it worked well for us one season as we won the league with only one batsman and 5 very accurate bowlers. ( I second topped scored for the season aggregate, that shows how rubbish our batting was)
It was boring though, I remember one game where we made 150 odd and the other team ran out of overs with there score in the 80's. The grounds we played on were tiny too so scores should have been a lot higher.
When I started playing back in Australia it was strange to see run rates of 5 or 6 an over and scores of 300 being scored.
Apparently back in the day there didn't used to be a maximum of 10 overs per bowler, and the club I now play for had 2 medium pacers that would bowl 21 overs each!! Scores would rarely hit triple figures. I'd have rather not played cricket than have featured in games like that, its awful. I don't mind being on the wrong end of a 400 run innings just because at least you're witnessing something interesting and impressive.
Scores of 300+ are fairly common at my club though. The straight boundaries are fairly close, and depending on which strip you're playing on there is one very short (and one very long) side boundary as well. Pretty much anyone can hit a 6 if they time the ball decently but that isn't to say its easy. The wicket tends to be very slow and low bouncing, and in previous years has been very uneven. But they've been doing some intensive ground work the past few winters to level off the square, and its definitely getting loads better. Having to drag a few tons of loam across it using a weighted ladder last November wasn't much fun though!!
