Hello, I have a friend that is really looking into getting anothe bowling ball.  He is determined that he wants a bowling ball that will get good length and a smooth but strong backend to it.  He is 6 feet tall with medium revs and medium to slightly fast ball speed.  He is right handed and I have made a few recommendations to him but I was wondering what you guys thought would suit him.  Some of the bowling balls that I recommended were the flash point, Detour, and the Formula.  It doesn't matter to him what company it is made by, as long as it suits his game for his style of bowling.  He also usually likes to stand in the middle of the lane and shoot between the 3rd and the 2nd arrow on the lane. It would be very appreciated if you would let me know your recommendations.  Thank you.
