here is my 2 cents
I would HIGHLY suggest rather than being told what to buy or recommended, Go to a few local shops and SHOOT a bunch of X bows,
they like rifles do NOT all fit everyone the same, have features everyone likes
or, are as user friendly or as LOUD or balance as well as others.
there is NO shortage of GOOD X bows on the market and prices can be from low to crazy high
I wouldn;t get super hung up on speeds either,, just learn the drop and your limits! and stay in them!
As none of them are faster than the speed of sound, so, ALL can be shot and have a deer hear and react to them,
which is also why I suggest SHOOTING several models to HEAR the differences between them! in sound of firing, triggers, and how much effort is needed or NOT to load and the noise involved tom load and Unload them!
the one thing I will suggest also is, TRY and shoot a few Reverse limb bows over just the traditional design limb bow
as for me, and this is MY personal experience(40+yrs of archery experience here)
is I find they BALANCE weight way better and I find them more enjoyable to carry and hunt with!
pretty much all the name brands make GOOD X bows, liability fears of law suits and lawyers force them to be safe too, HAHA!
but will only be as safe as the user, and how well they stay on top of basic PM"S and basic care of them! (waxing replacing of strings and so on)
some X bows wear strings out WAY faster than others and , should; be replaced as needed,
its one of the most common things I used to see when I had my shop (and my friends bow shops) and folks brought them, in, way past due to be replaced!
there is a TON of energy on them strings YR round and much more so when loaded!
not a pretty sight when they fail!
