Study habits: By hand vs. Online (FLEX)

I've been printing out my PTs and Problem Sets and notating most everything by hand (mimicking the notating that JY does during the lessons) but I'm wondering if I'm doing myself a disservice, seeing that the current LSAT is being administered online. I don't plan on taking the test until next year so wondering if anyone has any thoughts on notating in their heads for online study and/or what other methods you are using that might be helpful.
