This has been a great post to follow with plenty of good advice, I like courses that have variation in angles, elevation and lighting.
Now you don't need to elevate a shot greatly to help take advantage of any wind, again as mentioned place the longer target 1st even slightly higher by the use of 6ft post will have an effect.
Then change the angle and lower the second one stops any learning off the easier target.
I find lanes where the both targets are in a very similar line boring especially when the next lane again follows it with the same.
Pegging strings is another good one and placing the number a yard or a few directly in front of the target so it looks like it's next to it throws people off.
The old last target at about 8yrds followed by a full belter catches a few (My mate Chubby for one ;-))
Then mini kill at half yards as opposed to full eg 9.5 is a nother one I like
But in general make each shot as different as possible.
