I wonder if you could confirm my thinking regarding Gunn and Moore cleft densities, please.

If each model (Aura, Maxi, Six6 etc) has a fixed set of dimensions (the GM website gives the volume in cm3 for each bat type as a guide) then, presumably, the lighter the bat, the lower the cleft density.
A 404 (at the lower end of the grade and price spectrum; grade 3 willow) that weighs say 2lbs 8 oz will therefore be made of a significantly lower density cleft than an 'Original' grade bat (of the same model) that weighs, say, 2lbs 12oz. As we seem to seek out low density clefts on this forum (on our quest for max volume for weight), then a low weight lower grade GM at around �100 would seem to offer good value.

The above assumes the GM bats are graded on looks alone and not on some sort of performance measure (ping test with a mallet, perhaps?).
I hope the above makes sense and welcome your views, comments and insights into any other factors that I have overlooked.

Thanks,

David

I have 2 x octanes, one an original 2'9.4 and a 606 which is 2'7 and as you would expect the dimension of the 2'9 is much bigger all round.
so no the dimensions not the same

Thanks for the real world clarification.

There's 3 octane sat our club, one is mine.
Other 2 are 2.10, mine is 2.14.

They are identical in every way

I believe it's true that GM bats should all be the same dimensions, but that doesn't help your theory - remember why it is that low density clefts are sought after. They're wanted to make a bigger bat for the same weight. However if your two bats are GM Octanes of identical dimensions and different weights, there is no advantage in the lighter one - lower density clefts don't give a performance improvement just by being lower density. Of your two otherwise identical bats, the heavier one will perform better.

Thanks for some interesting replies and views.
Perhaps I ought to open a fresh thread, but to continue this direction of thought - Is volume of wood relevant to performance (other than perhaps the placebo effect of seeking a huge chunk of bat)? ie are two identically weight, pressed and quality clefts going to perform the same, regardless of volume?
I can fully see that a 2lb 12oz bat (other things being equal) is going to perform better than a 2lb 8 oz bat (if, for a moment we can assume the batsman's hand-speed etc is unaffected), as there are basically more willow fibres giving greater inertia.
Why do we seek low density clefts? Is it purely placebo?

I bought 2 icon 404's a couple of months ago. Both exactly the same shape, 1 was 2-9 1/2 and the other was 2-11

They're sought after because a lower density cleft can be used to make a comparatively larger bat. A larger profile, if done right, is stiffer than a smaller one, which should give better energy transfer from bat to ball and therefore better performance. Also because who doesn't want a bigger bat!

We are going to go down the bat speed to weight ratio trade off.

Weight behind the ball is weight behind the ball all things being equal.

Very nice article by the Doctor explains this http://cricketbatblog.com/2015/10/14/the-cricketer-article/#more-48.
