Speed is not everything. It should be the third or even lower demand out of your hunting bow. Consistancy and accuaracy are needed more than speed. You want to miss fast, wow what a story that is back at camp. Bow design is a science. Most dont know how to understand all that goes into a design. I am an engineer so I understand mechanical and parts design. There is always a trade in any design. Unless you throw all else out the window of reason and design something like you speed freaks want. A bow that shoots fast, only. A super fast bow can not be shot with any consistancy. As a matter of energy storage, the IBO Speed standards (70#, 30", 5 grains/lb) puts a mathematical cap on the maximum amount of energy that a compound bow can store. I know this sounds anticlimactic, as we're a culture of consumers who expect products to keep getting better, faster, more powerful, etc. But you must remember, the compound bow isn't powered by an external fuel , battery, or a computer processor. Despite the high-tech talk and anodized gizmos, your compound bow is still a simple hand-drawn weapon. Its output can never exceed the input it gets from the human body. The human body and the bow provide hard mathematical limitations when looking for a very fast bow with anything close to target accuracy. So naturally, we can't expect compound bows to perform faster and faster forever. At some point, the output of the bows will begin to approach the maximum input of our human body and it's influance in the shot, and then the speed race is over. This is the performance precipice of fact when design meets paper. I regret saying this, but we're essentially there now. A Super-Bow can't waste much energy on friction, noise, vibration, etc. It needs every little ft-lb of energy to be stored by those limbs and then successfully transferred into that arrow. If it loses just 5% in the transfer (6.49 ft-lbs), we won't have enough energy to make the super fast like 380 and more fps. We must also not mind a 0% let-off bow, and the harshest imaginable drawstroke (70# from start to finish). A high 300 to 400 fps Bow will not be for the timid. But you would get your speed. Good luck being anywhere near accurate because you wont be. So, lets look at your need for speed from a realist side and be real. At what point will you speed people say a bow is "too aggressive" or "too harsh"? Where is that perfect blend where bowhunters will think a bow has plenty of speed while still feeling that the drawstroke is smooth and comfortable? The basic single and softer hybrid cams, such as the Solo Cam, with IBO Speeds in the 300-330 fps range. These cams are more aggressive than wheels, ramping to peak weight more quickly and then coming to full let-off more abruptly. So they tend to store up more energy and shoot notably faster. However, a Medium Cam is still generally acceptable to most shooters. Most shooters will describe this type of cam as "smooth drawing," simply because peak weight doesn't persist throughout much of the cycle. For bowhunting and general purpose use, this type of cam offers a good blend of feel and performance. In my opionion this blend is exactly where a archer should want to be for accurate bowhunting. But go ahead and miss faster if you want. For Mathews to design a bow in the 340 FPS for you they would need to make use of the newer Dyad system. It is not what most would call a hard cam. A Hard Cam system, optimized for maximum energy storage and speed. You will notice how quickly the bow ramps up to peak weight and how quickly it transitions to let-off. You will also notice the distinct high-plateau where the shooter must draw the bow over several inches at peak weight. This type of cam geometry will store dramatically more energy, and will usually have an IBO Speed of 340 fps or more. The downside is that Hard Cams feel harsh. This is where Mathews design helps even out the storage of energy with the Dyad system. If your looking for a new speed bow design from Mathews, look not to the solo cam for that 340 and more FPS mark you want. Sure they have a bow that is suppose to be 340 in IBO solo cam. The Z Mag is a "ok" bow, it is not a great bow. Anyone who has shot an MR AVS design series bow or even the new Dyad design on the Chill will appreciate how much better the speed is achieved in the over all design of the Monster series than the solo cam. The solo cam "speed" bow can't match the over all preformance of a monster when shooting in the higher speeds. Ask Matt to give us another Monster Chill in the area of 6 inch brace with an ATA not less than 33 while pushing the arrow to 340 - 350. It will not be a great line shoot bow, but it would be a bow accurate and fast for your bowhunting needs. If you want a Solo cam bow, which are great consistant, accurate hunting bows, be happy with the 330 IBO.
