Wapiti: Your estimated draw weights might be a pound or two high, but maybe not. Depends on whether the bows stack much at your draw length. Since they don't feel heavy to you, no need to worry about it.
In addition to the quest for greater FOC that Oregon mentioned, in a lot of cases, it's just necessary to put a lot of weight on the front of carbon shafts to soften the dynamic spine enough get them to fly right. Also to increase overall arrow weight to a hunting weight of 500-600 grains. A lot of bare shaft carbons weigh 250 to 300 grains.
It would be more of a pain to get carbons to fly right for you than shooting your current arrows. You would likely have to add insert weight, and probably play around with broadhead and/or adaptor weight. Not really difficult, but it does involve some trial and error and buying different weight components until you find out what works best for you. Of course, you already know what works good for you in aluminums. You certainly don't need to make the change to increase performance. Your current set up will blow through anything on the North American continent.
I don't use fletching covers, but if I did, they wouldn't be made of wool. Too heavy. The feathers ends move a lot when the bow is shot and will damage themselves on the heavy fabric. To ameliorate the problem, keep the wool loose fitting.
I wouldn't use fleece either. Collects water and blocks the wind, and a good wind can play havoc with your aiming. I'd look for a cheesecloth/camo netting material. Provides the camo needed, it's light, and a breeze can blow through it without messing up your hold. Not going to protect the fletches from rain though, which can be a problem where you'll be hunting Rosevelts. Good luck.
