My experience with tuning and broadhead accuracy is pretty much like BobCo's. I've only shot my bow out to 40 yards with broadheads, but they were grouping close enough that I ruined one arrow when I was too lazy to go pull it before I shot the next one at the same spot. I am shooting ACCs with Blazer vanes, and they shoot very well with Slick Tricks, Muzzy 3 or 4 blade, or Phantom heads (all 100 gr.). The bow seems very forgiving, but performs very well for a 40" ATA bow with a 7.5" brace height, and a very smooth draw. I'm only pulling #61, and getting 65 ft. lbs. of KE. The bow is very quiet, right up there with any I've owned.

Coming from an Ovation, you will likely notice a bit more recoil. It is not bad at all, but it does recoil more than my Q2 XL did. Bare bow, it will vibrate a little, but with Limb Savers, catwhiskers, and a good stabilizer, vibration is pretty much eliminated. My bow did respond better to vibe control than many I've owned. I've also owned a Darton Rampage Express, and it did make more noise than the Tundra, but also tuned and shot very well.
