I'm not really sure how much a drop-away has helped me except for the fact that you can use full helical fletching and not have contact issues. I prefer to bare shaft tune, preferably to 30 yards. Once this has been done, I rarely have issues with broadheads flying or grouping well, unless there is something wrong with the arrows. This has worked for mid-90's Bear and Jennings single cam bows (with bad nock travel) up to last year's Bowtech Pro 38 dual cam which shot as close to perfect with broadheads as any bow I've personally owned. That bow had the often maligned Whisker Biscuit rest. That said, I doubt that anyone else on these boards has a bow tuned as well as Len in Maryland. He achieves excellent bare shaft flight, and excellent broadhead accuracy (and right with field points) with a level nock travel Darton CPS combined with a Muzzy Zero Effect rest. Of course, he also shoots better than most of us can dream about.

As far as that old Darton, the Lightning was the fastest bow of its day (early-mid '90s) and still shoots right with many of the fastest bows today, as long as you stick with medium-heavier arrows. I have a Viper which is only about 10 fps slower than my more modern bows with medium weight arrows. It still shoots very accurately, in fact, it is still probably the most accurate bow I have, at least in my hands. Modern bows are much lighter and more compact than those Dartons. Most are significantly quieter than the Lightning as well. Recoil and vibration on newer bows has also improved greatly. Most people today are looking for a shorter, lighter bow with less noise, recoil, and vibration than the Lightning. That is where the advances in technology are directed. If you would get a Black Knight 2 or Patriot Dually, I think you would notice an increase in performance.
