When your house lays a 10 board ditch, you'd be mad to be playing 5 board. You're playing where there is early friction, close to no area and you have to use a weaker ball to boot. Where the house lays a crown allowing you to play between 10 and 5 board, that's a different matter altogether. Dale grew up on Gosford lanes, which have that nice 5-10 blend, allowing multiple angles in this part of the lane. (Which personally is my favourite kind of easy house shot as it offers a variety of strategies instead of being slavishly forced to play inside-out to a breakpoint around 10 and working out carry.)
And let's face it, Dale is a merry handful when he can play out with some room, but it doesn't always work. To his credit, Dale can play lots of other parts of the lane, but like all of us, he's got his favourite bit, so we see him out there whenever it's a look. PBA players will tell you about "the Norm/Walter Ray Test." i.e. If Norm and Walter Ray aren't out on the edge, it's impossible out there. Don't even look. Maybe we'll have the Dale test soon.
We are all products of our environments. I grew up swinging to the edge with urethane, winning tournaments from there and averaging more than 220 for leagues, but today it's still not an "A" game over bellying a chunk of reactive gelignite on most patterns. Urethane just won't carry like the reactive ball beyond a few games, when it then needs to be aggressively cleaned. Even my Avalanche Urethane, which I consider to be one of the best urethane balls ever made doesn't carry like
any reactive ball.
Carry is a function of deflection and reactive resin just doesn't deflect like urethane does.
If you want a perfect picture of just how bad the THS blocked lanes have made us, in recent years I have met quite a few 200+ average bowlers who are scared of playing 5 board because of the risk of throwing it in the gutter. They are scared they'll miss by 5 boards. Yet they average 200+. You can interpret that as you wish, but I see it as a damning indictment on our game as a sport.
FYI - The other part of the Norm/Walter Ray test goes like; If Norm and Walter Ray are out on the edge, it may be possible, but maybe only for them! They are that good out there. I've seen Norm and WRW point right to left over 5 board with about 15° of tilt and throw big numbers. That's buh-luddy straight, btw!
