Put me down please.
In previous team productions I've been involved with some guys felt they were happier with say a par 5 than a par 3 or vice versa. Therefore when calling for names each was allowed to express that preference. Have to do it on a first come first served basis of course. When the pqr 3's and par 5's are exhausted then everyone else gets a par 4.
The other thing that caused some issues were someone not being able to complete a hole, often because unexpected circumstances cropped up out of the blue. If someone does go awol then everyone further down the list gets held up. In general things seemed to run better if a time limit for each hole was designated. If everyone takes one week that's 4 1/2 months which is a long time. Any slippage can make the project seem never ending.
Can each designer please have the freedom to create the elevations and any water features around the hole they are working on.
To preserve continuity will there be a set list of objects (trees, grasses and plants) to be used.
