Bow speed is a killer topic. My old Mathews is shooting around 289 ft per at my set up. I could spend $1200 and get 20-30 more ft per second, but why ? I dont shoot long distances out of respect. i want a sure clean kill, not a deer running all over creation with an arrow hanging out. To me a quiet bow is very deadly too. Lets face it, you only get one shot if you make alot of movement and noise. Have you ever shot one that continued to graze until it bled out ? I have, so I think my quiet bow is fast enough.
