It's a pro stock type of frame meant to be customized. 4g of lead at 12 and 3 in the butt and you have a damn fine stick on your hands.
Speaking for Ltd 315 18x20, adding extra weight doesn't work for me...
The racquet became too stiff (in the play of course, not in the RDC) and lost the nice feel it had before the customization.
I know that Ltd supposed to be "pro stock" type frame, but when you customise it turns to an ordinary stick...
That's why I said that Technifibre must fix the two basic Ltds problems (instability / low twistweight +/-13.5 and low swingweight / but sluggish feel far from 308 sw value) - but (and that the crucial !! ) keeping the same wonderful "factory"-feel.
Additionally, as
langdon0555 said, 11.7 oz static is too much for a real pro stock racquet.
Now regarding DC 315 LTD, I wonder if this 62 flex from the 20 mm frame is real...
I look at other DC models and all of them are +/-68, for a little more thick 22.5mm shaft.
