If you are new to growing big beefsteak tom's, don't be in a rush to remove the sideshoots.  Sometimes the plant throws up a large cluster of growth that looks like the leader but it can turn out to be a large truss and contains no leader.

Then you have to use a side shoot as a new leader.   :happy:   Cheers,     Tony.

Thanks Tony! That very thing happened with some of my Marmande luckily I had missed nipping out the side shoot.

the very same thing happened to me  but it grew a new leader quickly enough
