Not pruning tomatoes

...then there is of course the school that believes pruning is not needed as it is a lot of effort that makes almost no difference, and some even say it is counterproductive as it increases the risk for various damages to plant and fruit. Most agree that pruning should not be done to determinate varieties. Some say only the bottom suckers should be pruned while some say the top suckers should be pruned while the bottom few are left alone.
I guess it is up to each and everyone to do what they believe is best...
