I know that Hoyt makes a great bow, but I've never tried one...but will offer my experience with a carbon bow. Hope it helps. I have a Bowtech Carbon Knight. It weighs 3.2 lbs bare bow. I really like it for packing around elk hunting, light weight and 30" axle to axle. Not the most forgiving bow I've had, but not overly critical either...but I'd rate it on the forgiving side of the spectrum. (7" brace height). No issues at all with it if you're worried about the strength of a carbon riser. It has a bit of an aggressive wall to break it over. It does have a bit of a jump in the hand when it goes off. Very impressive speed out of it, I'm getting right at 300'/second at 65 lbs with a 380 grain arrow with my short 27.5" draw length. A bit aggressive cam system which results in what I'd call medium shot noise. It also is a little bit nicer for carrying on cold mornings and not freezing your hand as bad as an aluminum riser will. Several have complained about the grip in reviews, but I have zero issues with it and actually find it to be one of my favorites in comparison to some of my previous bows. I did have it go out of time and need an adjustment after a year of shooting it with the stock string (on top of the normal stretch from stock strings after 200-300 arrows). It is still wearing the stock string BTW (I got the bow as a left over in 2016), pretty good for a stock string. 3D season is starting to ramp up and I think I'll put a new one on it this year just to be on the safe side, although the stock string still looks pretty good.
A Mathews Helium isn't a carbon bow, but my brother-in-law has one and really likes it, it is about 3.5 lbs bare bow. It does seem to chew strings up a bit, an aftermarket higher quality string really helps it out. It is a very smooth shooting forgiving bow. Not real fast, he's getting around 270 out of it at 70 lbs, 27" draw, and a 390 grain arrow.
Both of these aren't brand new bows, but used or left overs can still be found. If there is an archery shop, North40, etc near you, best bet is to go handle some. Most places are willing to set one up for you so you can shoot them.
