Sweet toms

Hi all, long time no see, can anyone recommend a nice sweet tom please, last ear I grew 5 different variates and was very disappointed in the lack of sweetness in them, I don't know why I grew variates that were always normally sweet and juicy

What varieties do you normally grow ?

San Manzano (sp) ?

My top one for sweetness is Sungold but the skins can be a bit tough.
Gardeners Delight has never let me down.
I think plenty of sun is the secret as as Mumofstig said last years weather was not the best for sun loving veg.
