McDermott G Core vs PureX and other 'Low Deflection' Shafts

Hi guys!

I was looking at buying a McDermott G Core cue, and did some research and found some info on forums saying it was not a 'proper' low deflection shaft (and that their i2/3 shafts were).

I assume this is because the carbon fibre insert is around 6 inches long, not the full shaft length???

If this is the case, then this would also mean that most of the 'low deflection' cues advertised, such as Champion, and even PureX are not low deflection either as their inserts are, like the G Core, only at the last 6 or so inches, not the full length of the shaft.

I'd welcome any thoughts on this!

I guess the question you need to ask is what constitutes "low deflection." A Gcore shaft will be lower deflection than a maple but not has much as an I2/I3. Have you had the chance to hit either a GCore or I2/I3?

Agree...I have a standard maple and IPro shafts for my player while the wife's cue is Gcore. Hers plays MUCH more like my maple shaft than the IPro.

No it's not due to the carbon fiber insert, that really has nothing to do with it being LD or not. The PureX shafts have no inserts at all. 11.75mm PureX deflects about similar to the OB1 shafts with good hit feel. The thicker shafts are also LD but more of a "Lite" LD, over the table length they deflect about 2/3 of a ball off center. A standard shaft will miss the ball totally with side spin at the distance and speed I was testing things.

I don't think the G Core shaft is even advertised as low deflection. Nothing here about it being LD. In fact none of the McDermott shafts talk about low deflection which is a bit odd, just about "consistency".

Triple-Layer Carbon Fiber Core

The G-Core’s Triple-Layer Carbon Fiber Core extends through the first 7 inches of the shaft. This stabilizes the front-impact area of the shaft for increased control and predictability. This technology increases radial consistency, reduces vibration and limits the inconsistencies found in traditional maple shafts.

"Low deflection" is not an absolute, but a relative term. McDermott G-core is not low deflection compared to Predator 314, OB-1, etc..It IS low deflection compared to a vintage McDermott standard shaft with a gigantic ferrule made from heavy plastic.

Low deflection is a refrerence to how far the cueball is pushed off line when using sidespin, and need have nothing to do with materials. The materials are just a means to an end, not the thing in itself. You can make a completely standard shaft low deflection by cutting down the ferrule, turning down the shaft, removing the ferrule etc.

Where is Dr Dave when you need him? I'm sure he's in a phone booth changing into his superman outfit!

Expect the real answer scientifically supported shortly!
