You'll have to find what suits you, but I would suggest that you take off just 2 units of your usual jab, and have them in the morning. Wait a day or two, then take off another two so that you're having 4 in the morning. Same again after another day or two. Once you've got to 6 or 8u hold tight for at least 3 days (gives it a chance to settle without overlap so you can really see how it's working). Then if you need to, fiddle with another 2/3 units. At some point you'll find a good balance and stick with it.
I'd suggest writing it down as you go so that you remember what your dose is  Also aim to keep your jabs as close as possible to the same time every day, and if possible 12 hours apart. For some people it's not that important, but it can help to keep things smooth.
I think the basal testing is a great idea. One afternoon of hunger is worth it for months of settled BG levels  It's even better if you can arrange a couple of days beforehand where you eat regularly and exercise as usual, with some sort of routine, so that you can be a little more that other factors aren't changing your results.
