Nice, I am 1.78 and weigh 83. I am still not the biggest in my side but within school I am a beast ;) Seems you are the ideal size. But one small thing I'd like to say... GYM! Heavy weights, I think you can get stronger and more muscle tone which would help with the girls as well as rugby.
you are big for your height. i mean 70kg is the 'ideal weight' for your height but you play rugby so you are good for it, just work on getting strong :)
