You must remember that Mathews will be at least 1/2-3/4" longer than what the limb tag states.The Q2XL runs long,mine with a 27.5" cam draws 28 1/4".
To be safe I would order the arrows and the points seperate,then when they arrive mark where you want them cut,any shop should cut them for you then install the points.
There is nothing worse than having them too long or short.
