I think that the one reason why people bowl differently from centre to centre is because of how they think the lanes will be. If you think the lanes are hard, then you are more likely to bowl bad, compared to going to a new centre and saying to yourself, these lanes are easy. As people have said before, different centres suit different people.
So if someone tells you that a certain centre is hard, ignore it because unless they are exactly the same as you, it might not be true. Timmee and myself are examples of this. When you walk into a centre saying Ow its so hard, i cant bowl here, crap conditions, etc.(not that timmee said this) there is a good chance you'll bowl crap.
I did this last year at Redcliffe, i finished with a 170ish average. I went there at the beginning of this year not thinking that they were hard and now have a 200 ave. Im guessing this is the same as Timmee.
You should walk into a centre not thinking that it's easy or that it's hard, but that you need to find out for yourself what the lanes are like.
Anyways, thats what i think.
And Feral, why should jl grow up, he didn't mention any names. Therefore no one was hurt by the COMMENTS and thats all they were.
