This ball is a great ball for all condition I have mine set with the pin above the ring finger with a weight hole it's set up to go long and finish strong.I  bowl on a easy pattern what we call the christmas tree because with heavy oil in the middle and the outside dry it can't get any better for bowlers.Still if you want to carry you need the right ball.I bowl my first 3 games shot 775 and after I bowl in a other bowling center where the carry is tougher but the condition are still fairly easy if you keep moving PS: every 4 frames.My average is 17 pins lower there only 213 but I use the rsx for 2 night and on those 2 I average 240 and I'm high average at that house.The ball hits very strong playing inside or outside.I bowl a tournament on the weekend I use the Saturn mostly but when I  move inside I wasn't getting enough back end reaction so I switch to the rsx and on my first game ever with it in a tournament I bowl a perfect game it was the only one of the tournament it wasn't easy there was not much hold in the middle and speed was critical the best part is I had enough confidence to trust that ball even tought I did not have many games bowl with it.I was 50 pins down on the match 2 game total pin fall and came back to win now that is a great feeling to see a ball carry even on a sport shot.this ball can create a lot of room for error if you are the type of bowler who look at a area and crank the ball fairly hard you will love this ball I'm more of a stroker but if I want some time I can hit it more and change my hand position and the ball those what you expect it will go longer and hit harder.When you play with hand position hand the ball does what you want you know you have a great ball.My favorite ball in my bag.

Review:  I have used this nice piece on a variety of conditions.  I mainly use it for med to med heavy more on med heavy side  Havent really used much since the purchase of my second epic battle that i polished!!  This ball needs head oil to get down the lane and then has a nice strong arc type finish with above average hit and carry keeps pins very low, not quite as low as the mercury but low enough to carry majority of time.  The only time I put this ball up is when the heads break down other wise it wants to move early and loses all its energy.  But there are other balls for that.  OVer all this ball is great piece of equipment at an affordable price.  give it a solid 8 of 10.  Keep up the great pieces ROTO!!
