Bear take down bow

[Elements]

Can someone please tell me what the difference is between Limb 1 and limb 3 and riser A and riser B on the new Bear takedown bow.

[Blackhawk]

A handle (16") with #1 limbs-56",#2 limbs-58",#3 limbs-60".

B handle (20"),with #1 limbs-60",#2 limbs-62",#3 limbs-64"

I listed #2 limbs, but they are no longer available, but all Bear limbs will fit all risers...at least 99.99% of them.

Thanks for the information.
