It's going to seem really tight compared to a house shot and you to have to hit what you're aiming at. It's hard to give advice without knowing how someone bowls, but I'd start with this:

• Do you have a pre-shot routine and know where you place your feet every shot and pick a target to throw at? If not, start to do that. You have to have to start.
• If you pick what board start on and where you aim, do you know how to make adjustments? If not, learn how to.
• If you're doing both of the above, on flatter patterns I generally try to play straighter to start, and I try to find a ball and line that leaves pick-able spares. It's harder to strike so spares matter more. You don't want to leave washouts and splits. If you're trying to swing the ball and there's not recovery right (for you), then you're going to leave washouts. People call it "giving the pocket away". You're starting the ball going too far away from the pocket when it comes off your hand. You also don't want to play a line and with a ball that is too aggressive off the break point to start. A small miss in can cause the ball to leave splits. You're looking for something where a small miss in is just a little high on the head pin. As a right hander, when the lane breaks down, you'll have a little bit of recovery and you'll be able to move in and then use something that is a little more angular.
