FOC for Cartel Triples

The lighter the point the lighter the arrow and thus more speed out of the bow (though a string with more strands would be slower) Heavier points would stabilize/counter-act wind effect/ wind drift.

If it were me I'd invest in the 500s and increase the poundage the little you want, keeping a heavy point weight like 110/120(if you can get them)

Erm, correct me if I'm wrong, I thought that Cartel spines ran the other way to Easton etc. i.e. 600 is stiffer than 500.

The 600 and 500 being the weight (grams) required to bend the arrow by the same amount.

On the Charts I have seen for the triples Here the lower numbers are stiffer spine and heavier arrows.

[greydog]

Morphy, the 1100's are the weakest at 5.86 grains/inch and the 300's are the stiffest at 8.18 grains/inch

MikeD, yes that's correct, all those methods will increase the weight slightly, from 8 grains or so for a pin or medium wrap, to 10 - 15 for heavier fletchings. If you can trim the shafts that would be your best choice.

Its quite simple and as said before arrow dynamics are explained on Joe Tapleys web resource. Always shoot maximum point weight. But if you need to change for a tune or need the distance then these must come first. People who say its too heavy are old fashioned and ane hung up on the hoyt arrow chart usually.

Ahhh. You fell for the (false) description of how Cartel measure spine.
Well, actually, Cartel may well measure the spines that way. But if they do, they don't use the figure they arrive at as the number on the shaft...

Just like with the Easton shaft numbers, smaller number means stiffer shaft. Unfortunately, there isn't a direct relationship between the Easton and Cartel numbers. It's just that the way they chose the numbers makes you think there should be. It would be easier if Cartel had just called the shaft sizes "1, 2, 3...". People wouldn't get quite so confused then...

there isn't a direct relationship between the Easton and Cartel numbers.

There has to be a conversion between Cartel and Easton Spine measurements via the shaft stiffness (EI) value. It's just that nobody's bothered to work it out.

Rather like the 1,2,3 idea if you could get Easton and Cartel to subscribe to it. "I'll have 12 number 5s please!"

hmmm. You're assuming that the Cartel number is somehow derived from the stiffness of the shaft, and that the Easton number is...
I'm not sure I'd make that assumption without independently documented proof... As it is, I'm not sure you can strictly make a comparision between the numbers on different models of Easton shafts.
