which bow

Im perfectly aware that any bow is fine and everyone uses something different. But I am curious about the pse line of bows, specifically the wave and the discovery. what makes the tidal wave worth $100 more and is it really worth me spending the extra. i have plenty of money to get one i just want to know if it would be a waist of money and time and if i should just buy the Discovery package instead of the Tidal Wave package. thanks for any and all input!!!! if you have something better in mind the the two i have stated then please share also!!
