Those are all the options for me for the bow I want to buy. It's a Samick Polaris 62"
My draw length is 26" and I wan't the draw weight to be about 30 pounds. I have bolded and underlined the numbers that I am confused about, what do they mean and, if possible, which choice would be the best for me? If you need more info then just tell me!

one word as additional information:
Those weights written on the limbs are the weight you would pull if you pulled 28" long.
So lets say you have a 66" long bow with limbs written "30#" on them (at 66" long) then you wouldnt pull 30 lbs at your drawlength. with 26" you are 2" shorter than the convention. So i would go for 32# @ 66" to get around 30 lbs drawn at 26" instead of 28".

the risers normally come in 3-4 different length's:
21"
23"
25"
27" (New)

the limbs come in 3-4 different length's:
(children)
Short
Middle
Long
Limbs differ in 2" each step except children...

If you combine a 25" riser with a long limb, you get a bow of 70" length.
If you combine a 25" riser with a middle limb, you get a bow of 68" length.
If you combine a 25" riser with a short limb, you get a bow of 66" length.

Same game goes with the risers of 27", 23" and 21".

in the example
Samick Polaris 62"/66" Limbs 62" 39-40/66" 37-38 +$53.99
it will be a 21" long riser with either long or short limbs.
With the 21" riser + long limbs you get a bow of 66" with a weight of 37-38 lbs @ 28" drawlength.
With the 21" riser + short limbs you get a bow of 62" with a weight of 39-40 lbs @ 28" drawlength.

If i had to choose (as we do for our youngest members in the club) i would go for a
Samick Polaris 21" (gives 62"/66" bow) with long limbs to get 31-32 lbs @ 28" draw. with your 26" that should be in the ballpark of 29-30 lbs drawn.

The weight can be adjusted a bit (in the case here yround 1 lbs) with the big hand-screw holding the limb to the riser.

Hi,

What I am unable to understand is why the shorter specification (62") has a higher draw weight yet the longer specification (66") has a lower draw weight. Assuming a pair of each of the listed limbs are attached to a shorter riser to get a 62" overall size, and a longer riser to get a 66" overall size, what would be different about the bow string to make 62" bow stronger than the 66" bow?

Thanks!

In archery, it often helps to think about extremes:
What happens if you attach the 1m long limbs on a 8m long riser (10m long bow) and pull the string back 1m? The limbs wont move much because the angular movement the limbs have to do is very low. I think that would be around 10° angular bending

Now we look at another (medium) Situation: 1m Riser and 1m Limbs = 3m Bow. Pull it back and the limbs bend much more than on our 10m-Bow. Maybe around 25°

Now the other extreme: 1m Limbs on 0m Riser = 2m Bow. Pull back one meter and the limbs have to bend around 45°. Again much more than the 3m-Bow and MUCHMUCH more than the 10m-bow.

Thats why the same length of limbs on longer risers bend LESS than the same on shorter risers.
And less bendage = Less poundage with the same limbs.

Also: the samik polaris are a good starting point. We have over 25 of those in my club in different sizes and weights for our starters or events.

Be sure you also get an arrow-rest for them. They arent really this good for shooting off-the-shelf as we found out...

they are the limb thickness.
I think?
No. Not really... At least not directly.
They are the poundage at 28" drawlenght with different riser-sizes and lim-lengths.
62"/66" is the length of the bow limb 62 inches or 66 inches
the 37-38 and 35-36 is the pounds draw.
so the 62" 37-38/66" 35-36 means
the 62" limb bow is 13 to 40 lb draw and the 66" limb bow is 13 to 38 lb draw stringht.

so if you want the 30 lb draw weight you want 62" 29-30/66" 27-28 or the 62" 31-32/66" 29-30.
