hi,
congratulations on your purchase you won't regret, the way this pulls at 1100g is plenty, there is no evidence to say that going higher will bring you gains quicker, its all about time under tension.
i haven't moved from 1100g and when your doing this 6 hours everyday, the fatigue becomes unbearable, eventually you have to keep changing angles to get some rest. do not worry about the weight
once you feel the stretch all will become clear, i have done it all with the massive loads over the years does not get you there any quicker, more likely to lead to an injury, just think of this being a marathon your competing in,
its a long road and only the toughest mentally will survive and reach your goals. lower tension, longer hours and hide the measuring tape.
