Limb Stacking ???

[Big Boy Blue]

Hi

I am currently thinking about what limbs to get next and I have seen comments regarding limb stacking in various discussions.

Would somebody please explain what they mean by this.

Thanks

Hi Phil

Stacking is used to describe a limb that has a rapid draw weight increase around the end of the draw length. So at around full draw length it is really hard to pull.

New limbs at the top of the range are allegedly designed to be "soft" around the full draw point see the adverts for Winex and G3 limbs.

Border limbs are also reputedly good for this.

Try some limbs for yourself.

Thanks for the enlightenment.

I have just aquired some W&W Everest Pro Limbs (36lb) and they seem to be extremely even through out the length of the draw, is this then what is called a smooth limb or is that something else.

Its kind of interesting as I had seen a couple of people say these limbs stack at around the 23"/24" mark. Even with my very novice arm, it does seem to be a gradual increase in load and I certainly cannot feel any areas where the limbs get more tough to continue the draw. I have even tried a inch of overdraw and its just as even.

I guess in the end its just done to finding something you like.

I think Samick Extreme does stack. At my 28" draw I can really feel the stack.

I used to shoot 31inches of arrow @ 40# from a 68inch bow (Trainer), then had a 70inch Hoyt GM with Samic limbs S M O O T H in comparison to the 68" I was told that using the longer limbs, stacking was now a thing of the past. I have never questioned this since,,, but, am I right in thinking that it is the length of limb that reduces stacking?

Stacking is not a function of bow length - HOWEVER - heres the BUT - with a longer limb there are 2 effects - a better string angle and these limbs are designed for longer draw lengths - so the 'sweet' spot is at ~ 30" Medium at 28" and short at 26".

KG will even do you a 72" limb !

Like I say, It is something I've never questioned since, & believe it or not, it is something I have not heard of for years, so thank you for the information.

UMM 70" is long enough for me thank you but I have come accross someone who could do with a longer limb, I'll pass it on. Cheers

And I always thought limb stacking occurred when Quicks bought in a job lot...

a little clarification on stacking. It's bad if it happens at the end of the draw. Not so bad in the middle.
It's all to do with whether you get any benefit from the weight you end up holding. A rapid increase in weight at the end of the draw does you no good, as it has little effect on the arrow speed (when you release, the arrow gets the extra weight for a short period of time - doesn't accelerate much). A rapid increase in weight earlier in the draw might do some good (think "compound" - a lot of weight goes on early and is acting on the shaft for most of the time after release). So a limb which stacks *early* might be preferable to one which stacks late (relative to your draw length). It could be said that limbs like the G3 (and some of the other modern limbs) stack very early, to get higher arrow speeds.
