Keep in mind that when you open the canopy you will create cover, but you will also create food in cover. This may or may not be what you want. Creating food in cover can make deer more sensitive to hunting pressure.
Another thing to consider is wind. It sound like you are on a slope. Thermals will rise in the morning and fall in the evening. So typically one would want to be above the bedding for morning hunts and below for evening hunts. Before you create bedding, consider your travel routes to and from morning and evening stands. There are a couple options and some have been mentioned. Hinge cutting will create instant browse by making vertical food horizontal. With this, you are leaving the trees in place. Another option is to create "mineral stumps". With this method you could leave the tops or remove them and you can use the wood for firewood or sell it. The MSU deer lab has a good podcast on "mineral stumps" but basically, the stumps resprout and the large root system concentrates minerals and nutrients in the limited amount of leaf matter the water sprouts provide. Deer seek them out. They also quickly provide cover.
Another option is to remove the trees and tops (you can do mineral stumps with this method), create firebreaks, and execute periodic controlled burns. The reason you remove the wood and tops is to reduce the fuel load. The burns expose the soil to the sun and encourage herbaceous plant growth. Burning every few years can keep this in early succession for a long time. Using fire requires a bit of know-how but most states offer classes and in some places you can contract it out. This is probably the most work up front if your timber is not marketable, but will sustain bedding (with food) for the longest time.
Keep in mind that all cases you will be creating human disturbance and changing habitat on a large enough scale to change how deer relate to your land. This is, of course, your objective. However, it will take time for them to change their patterns the way you hope (if they do), and in the interim, hunting may be unpredictable.
