If you notice the total weight with the muffler for the Saito 100 is 20.9oz with a power output of 1.8hp. That is an awesome power to weight ratio when compared to the O.S Surpass 120 with a total weight of 33oz , but with a disapointing 1.9hp when compared to the lighter and smaller Saito. The O.S 120 only outpowers the Saito 100 by .1hp, but the O.S is more than 12oz heavier. I am not trying to say Saito is better than O.S or vice versa, or start an arguement. What I am trying to say is that if you use the Saito 100, and use 9oz of lead in the nose that you would still be lighter than the O.S 120 that only has a very small fraction more power according to specs. Just some food for thought.
