For 100% on 49...its possible
1st shot... shoot a very very high arcing shot that comes down on the lightsaber on the very bottom row. very difficut, will take a lot of tries.
2nd shot...careflly arc a shot between th ebomb and pin in front of you to pick up the tri-shot and hit the ight saber ahead of it. this will cause a chain reaction that should leave you with two balloons, a bomb right in front of you, and an ice balloon in the lower right.
3rd shot...also takes lots of attempts. you should be throwing the three in one dart now. if you aim to just graze the top of the bomb, with nearly full power, the bottom dart should hit the ice balloon, giving you 100%
Alternative solution for 47 that doesn't require crazy shot.
1. shoot bomb right in front of you.
2. arcing shot hitting pin closest to you and center bomb
3. aim slightly above the center pin at nearly full power to hit center pin and have the dart bounce off the rubber thing on the right and hit the bomb on the right.
4. (most difficult shot). you should be left with three or four balloons on the right. it is possible to angle a shot through all four of these balloons that also hits the two farthest left balloons in the top row of the section of balloons in the upper right and hits the pin in the section of balloons in the top right, giving you the required total of 41.
