RE: Aluminums???
ewolf, I said 'fine tuned' not micro tuned. Frankly, the bows I prefer can't tell whether they're fine tuned or micro tuned. They shoot great. Easy and less frequent tuning, not to mention accuracy, is exactly why I prefer them.
When was the last time you set up a deflexed riser/long axle to axle/round energy-wheel bow?
