Surfing Waves

hey...i have 2 questions first im 5'9 135 pounds and i hav nooooo clue what wetsuit i should get... im not skinny to the bone im pretty muscular as u kno i play tennis lol...well the other question is how far should i be up on my board wen im paddling into the wave?

Best thing to do regarding the wetsuit, is to try a few on first, also it depends where you are surfing to what thickness you need !

I have my feet just over the rear edge of my board when paddling !
