i've bowled a 289, 279(3x's), 278(2x's), and 277.....but no way i could bowl backwards haha......i've been bowling since i was 5, i bowled my first 279 when i was 14....and i stopped bowling because of school....I only bowl about 1 time every 2-3 months now, but i'm still consistent. i bowled the 289 about 3 months ago actually...if i kept bowling, i probably would've gotten a 300 when i was 15
