At the start of last year, I had a coaching session/ club evaluation on a launch monitor with the local pro. I had about the same clubhead speed for my 42" 5 wood, 43" 3 wood, and 44" driver. That was eye opening.
I've used thrivers and monster 3 woods. My latest was a Ping Rapture 3W. My results were that the 460 head does better. It launches higher, must be due to tee height encouraging a better angle of attack. And it probably spins less. The 460 would go 10-20 yards farther. But for a person who has a downward angle of attack, I wouldn't be surprised if the Mini type club goes just as far as the driver, and with more accuracy.
