Cabers - How big is to big?

My caber supply is running low and I am starting to make cabers from a supply of dry cedar and pine logs. 

I have finished making my first caber which I have to use this weekend -- It is 18' long 110# pine caber with a caber score of 840.  The weight/length ratio of 6.1 -- There is not much of a taper.

This seems to be a good Caber for A's.  Am I correct?

What size/score is unturnable?

Are the values in the table at the below website (Scottish Heavy Athletics) still good reference values?  I ask this because I am seeing bigger and heavier cabers being turned as the competition in the games increase.

Thanks for your help.

I appreciate your thoughts, but how many cabers have you personally scored or checked to macke sure that they were calculated correct?  I have made several cabers (I would be interested in how you make yours) and scored and verified many more.  although there is some deviation from caber to caber, I feel that the system does give you a good comparrison from one caber to another.  I other words; if you have a caber that scores 800 and you turn it 9 out of 10 times, you can be confident that when you get to a games and they have one that score 800 (even though it is a foot longer and a little heavier ((it has a higher taper factor) that you should be able to turn it.  Now I will give you that I'm assuming that the AD has run the numbers properly.  This is the best system I have seen to be able to compare caber to caber.

On the other hand if you throw in the east and are used to hardwood cabers and can turn a 19 ft. 130# caber and then you make a trip to the western states and you get a 19ft. 130# Lodge Pole pine caber with very little taper: you will find out that going by length and weight only does not compare two different cabers well.

I would love to experiment and test out another system or equation if you come up with one.

there are other factors that I believe you just cannot calculate and compare between cabers:

Caber "flex", any bends or warps in the caber, the "handle"  I find that a stick that has a handle that is small enough to fit into my paws is easier to control and turn than one that has a large handle or no handle (if it is just cut straight and not rounded).

Just my 2 Cents
