Started playing after a long hiatus several years ago and bought a 1885 GM with the lightest pickup imaginable - bat weighed 2.6 fully dressed(one grip, toetek, face sheet) The idea was that I did not have the strength to wield a heavier bat effectively. However, Could not get anything off the square with this bat - Moved to a 2.15 block of wood later in the season and played much better.
Since then, I have had several bats between 2.11 to 2.15 and seem to play well with them. I have found that the margin of error (mishit shots) is very small in the lower weights with less willow. Also, mishits result in significant jarring shock to the hands (at least my experience). With added weight you kind of give-up the cut shot to the fast bowlers but gain advantage on mishits and drives. And with the quality of balls and fields here there is not much value in well timed pushes along the ground -(Read long grass and lower quality league balls)
Long story short, 2.10 - 2.13 well balanced is what I will play with!
