I have two fullsplice cues from Sly. One purpleheart/maple and one ebony/maple.
Both with juma joint and 3/8x10 pin.
The stiffness is in the medium range.
I think Mezz cues plays pretty stiff, Sly`s cues plays a bit softer.
Both my cues are bumperless and have a nice ping sound to them.
I play with a McDermott i3 shaft, right now i have a ultraskin medium tip on it.
