I've rammed cutters with my corvette, so i know how effective it can be. The problem is that the only way your build will kill anything is by ramming it first.
If you are not A rating the thrusters and PD on your corvette, then you are better off flying an A rated FDL or FAS.
here is mine

weapons loadout changes based on the mission and personal preference, but there are always pulses or beams involved.
Your weapons loadout is not the only thing I would criticize in your build. Here are the other things I would change
7B fuel scoop - a waste of money on a budget limited build, especially when that is your most expensive component. 18 million extra to refuel 15 seconds quicker.
4B FSDI - too heavy. Change to A, C, or D rated
Point Defense - pointless in combat unless you just like seeing it shoot things
8C powerplant - 7A saves you 40T of weight
Heat Sink Launcher - Your build only needs 1 since you are using both SCBs at the same time.
7D thrusters - Not only do they make you go faster, but they affect how fast you can turn. If you downgrade your fuel scoop, the money saved can be spent here. 7B thrusters are only 13 Million more and you can save 18 Million buy going to a 7D fuel scoop.
