Static Iimb is an age old design brought up to date with fiberglass and laminations.The benefits of the static limb is smoothness, no hand shock, and very quiet with the right string only 2 1/2 pounds per inch.  The design keeps the string angle low which keeps it from stacking.  A static limb stores more energy and stacks less than a full working limb.Its speed is about 212 FPS depending on release with a 540 grain arrow, speed, cast, and flatter shooting goes altogether, all using B-50 string.  The static limb also shoots heavy arrows with no problem.  It is also much easier to string and unstring, you will be less likely to twist a limb or break a tip.Static limb design stores more energy at full draw because the limb tips DO NOT UNCURL, making this design a very hard hitting bow.  This limb design has a low brace height, by having this the string travels longer with the arrow and transfers more energy to the arrow making a fast, hard hitting bow.
