I have owned three Excalibur models over time.
All were tack drivers.
All were very easy to work on.
The rope cocking device works very well.
I now have a Matrix 380.
It is the last one I will ever buy.
The Matrix series is much more narrow than the older Excal's, and the new Micro's even more so.
My current bow is tricked right out.
TriggerTech Custom Trigger single action at 1.75 lbs.
Aftermarket Hawke Scope.
Custom Boo Strings.
Only shoots custom Zombie Slayer arrows with Luminoks.
Will hit a beer can at 100 yards every single time.
Deadly on deer within hunting ranges - pretty much guarentee a pass-through each time.
I personally avoid wheel bows as they are a nightmare to tune / restring.
Cheers & Good Luck with your choices!
