well I am sure aging is and will get to us all at some point
but I do know that there can be things going on with equipment that the eye cannot see, and limbs are for sure one of them, have to always wonder , or I do, how long they can store energy and memory, as once lopaded thats a LOT of pressure being held on them in my eye's over yrs I HAVE to think they loose some of it, and wonder even more if they do so in an equal manor!
but I again agree your groups are plenty good to make clean kills
something you may or may not like, but mechanical heads that open to bigger size than your muzzys can help add a little extra give on shot placement too
them 2.5 inch Rage heads whould fly fibe from an X bow and at 20 yrds you would have tons of energy for a pass through
not one to say bigger is better, but it cannot hurt either
I know you like your fixed heads, and have trust in them, but it could be something to think about
and yes ALL X bow's to me could sure benefit from better factory triggers
all the mroe so on some of the one's that cost so much money too!, don't really have to be lighter, just less over travel and cleaner breaking
they need like an accu trigger on them , so you can have an extra safety too and still have a good trigger
