Me too. I ended up with string jumping issues. I did everything I could to quiet my Martin Scepter with overdraw, but string jumping was still an issue. Even back then I didn't have penetration issues with properly placed shots. They were all pass-thru. However, one day I made the mistake of letting a bow shop owner talk me into shooting a Mathews Switchback. No overdraw, shot faster with almost no noise or vibration. Walked out with a might lighter wallet and new bow. The old optical range finders were hard to use in low light. Back in the day, speed helped. Since I got the switchback, I've never had a deer jump the string.
Today, speed is secondary. Slow bows, by todays standards, are still faster than we had back then. Noise is still an issue with many crossbows. Many manufacturers seem to focus on speed that doesn't matter and ignore noise. Mission is one exception. Today, you can even buy a scope for a crossbow with the range finder built in. Shooting a compound under hunting conditions is still a challenge. Maintaining form at awkward positions under cold conditions can clearly put shots in places where penetration can matter. I find that a much harder argument with a crossbow. The only issues I've had with errant shots with a cross bow are when the deer moves. That will place a shot further back, not a bony area.
But, we all have different hunting conditions. Some will favor penetration. I favor blood trail.
Thanks,
