CorBlimeyLimey is correct about jogging.
Consider the readabilty of your drawing. Lines that are too close together are hard to read, even if you can make out the dimensions.
Consider running ordinate dimensions down both sides of the part.
Do the new versions of SolidWorks support tabular dimensioning?
Since it is SolidWorks and you have a 3D model, there is nothing to stop you from having multiple copies of the same view. Each copy can show a different, complex set of holes. This is a drastic solution, but I have been there.
