i think for spacing, use your lasers as a "feel-out" of sorts. when approaching with shl, you don't have to go straight at him. maybe go in a ways, and then hop right back to the other side of the stage. you're in no way obligated to attack until you have a good opening. so while camping like a ***** is bad, and you shouldn't do it, keep pressuring, coming in and out of attack range, until he makes a mistake, because trust me he will. /runon to the max
EDIT: your tech skill is reallly good. the only thing to look at is that you go straight into shine from the dair by reflex. its not a bad thing, but you should at the very least make sure he's in shine range, a lot of times you were clearly not going to hit him with it and did it anyways. learn to judge whether or not using the shine will help you from a dair.
and if it won't, usually i would use a dash attack, because you've got a clear shot at them and dash = combo.
