You could try adjusting the map to assign a little more of it to the bottom of the column; that may improve the resolution.

Here's the LSL script for setting the mode to cylindrical:

default
{
state_entry()
{
llSetPrimitiveParams([PRIM_TYPE, PRIM_TYPE_SCULPT, "copy and paste texture UUID here", PRIM_SCULPT_TYPE_CYLINDER]);
}
}
