The "One bow to do it all" IMHO would be much closer to the full out target rig (Hoyt Pro or Ultra Elite) rather than a more hunting oriented rig.

For years people hunted with bows in the +41" range with little or no problems. A bow shooting under 240fps kill deer or elk just as dead as arrows moving 300+ fps.

On the flip side of the coin, your 32" ATA bow is not going to be as at home on a 20yard indoor range as your 41" bow will be in the woods.

If I were forced to choose one bow, it would be a ProElite with XT3000 limbs and the new SpiralX cams.
Accuracy is accuracy, on the range or in the treestand.
