The Whisker Biscuit will slow your arrows down but if set up correctly it's only about 1-3fps...you won't even notice. It's a great hunting rest. As for the sights It all depends on what you like. You don't need an expensive sight to kill deer. Again if you are only hunting you can spend anywhere from $30.00 to $50.00and still get a quality sight. My hunting bow has a Tru-Glo 2000 sight on it. It was about $50.00 (Tax Incl.) and has an all metal body as well as a one piece sight window/guard (the guard does not screw on) It has the Tritium glow pin for the 20yrd pin. it's light, rugged and simple....perfect for hunting. Both combined will run you under $100.00
