I have neither 300 or 800. I would take an 800 series over 300 game any day, in fact when I show up for the night to bowl I hope for a record 3 game average of 267 but I don't think about it.
The closest I came to an 800 was 775. Shot 279, 279, 217. 3rd game got started and had a quick front 4 then 1 wheel fell off. Thought okay I can still do this after a weak 7-10 leave, couldn't recover after that.
No honor scores or 11 in a row to my credit although I do have 11 in a row unsanctioned that was posted on the records board above the bar window from when I shot 290 on the Cheetah pattern during a summer league.
