Cheaper is the only way I wish they would go personally.

Ain't gonna happen. They've got to charge a bunch more than what bows 'should' cost in orderto pay for all those bows those idiotspeed freaks are tearing up with ultralight arrows and sending back for warranty work. [8D]

The sensible guys who don't abuse their equipment and shoot moderate weight arrows, who never have to make a warranty claim,are actually buying several sets of limbs and spare parts for the speed freaks every time they buy a bow. As long as the consumer demands more and more speed - for reasons totally beyond MY comprehension -then the prices will continue to skyrocket.

Thanks for the lesson!

I'd love to see how you calculated it, but it matches what I have seen elsewhere

Actually it's pretty straight forward. If the bow is a 30" draw and an 8" brace height then the power stroke is 20 1/4 inches or 1.69 ft. If you pull 70# over the entire power stroke which gives the absolute maximum stored energy possible you get 20.25 x 1.69 = 118.42 ft/lbs of stored energy. Now if the bow transfers 100% of it's energy to the forward motion of the arrow, the amount of kinetic energy on the arrow is also 118.42 ft/lbs. Now since KE = 1/2mv^2 and we know the KE and the mass of the arrow you simply solve for the unknown v = (2KE/m)^.5 So in the example I used for a 350 grain arrow it comes out to 390.3 ft/sec and a 600 grain at 298.1 ft/sec.

Even with a 0% letoff bow, which climbs to max poundage very quick and stays there, it MIGHT be doable, but would be unshootable.

Nope, not even if you could manage all that. At least not at 70# peak, 30" draw, 8" braceand 350 grain arrow.

UNLESS some new technology comes along that actually creates energy during the shot.

I think that is called a firearm. ;) Actually that's not true either. Turtelshell is correct, you can't create energy, the best you can do is carry a bunch of it with you. That's what we do with a firearm. We carry the stored energy in chemical form in our ammunition. In archery, we carry it around in chemical form in our muscles. Unfortunately, even the strogest of us are pretty limited.

Actually, I just noticed a dumb mistake in the explination. It's not 20.25 x 1.69 but rather it should have been 70 x 1.69 = 118.42 ft. lbs. Sorry about that!

RE: where can the bows go next ?

Lighter weight risers with limbs that store more energy. New materials for strings that will reduce stands and stand size creating more speed. Cams that preload the limbs and increase energyover theentire powerstroke.

RE: where can the bows go next ?

That does add up better. Just saved it for further referencing and would have been a little confused then.:D

Well, with that bow and a Muzzy 100 grain I almost put it through the spine completely and no breaks on the blade, so no need to change! [8D]

I'll keep my 271 fps and put it in the vitals!

RE: where can the bows go next ?

What about a little nano technology?

Some composite carbon-tungsten alloy risers that weigh less than 1 lb with a material structure that counteracts vibration at the molecular level? Granted if they built one today, it would cost about 1.5 billion each :D But that sort of technology is coming.

Nano machines are also being developed that can react to light. Eventually you could have a camo coating that mimics your surroundings like a chameleon just like in "Predator."

And how about a string and cables made of something like spectra fishing line? 1/5th the diameter and mass with all of the strength? That would have to be good for a few fps? ( I know, spectra cuts easily, I'm just using that as an example!)

What about an inertia driven expandable head, maybe with a mercury core that deploys the blades sort of like an airbag?

RE: where can the bows go next ?

I think we may start too see Titanium risers,very light and tough. Unfortunately also very expensive[>:]

I suppose I could see that happening. I'm wondering if we don't come out with some sort of carbon/fiber riser, reinforced by something. Dude, I don't know where the heck there going with it. I'm not an engineer and don't intend to be. I just like enjoying the ride;)
