rugby is awesome, go for it
Rugby requires 3 things; physical presence, mental fortitude and toughness. You sound like you have the first but do you have second two? the best rugby players are not the strongest nor the fastest. The best players have all three attributes, so if you are big and can run and are reasonably smart and you can play through pain then trial for this team. Still not sure? Let your mates who play rugby be a guide. They know you well and they should know if you have what it takes... Good luck.
