Hmmm, after seeing aluminum bolt failures on other DA engines, any that I've owned were changed to steel bolts. I believe DA released their 60 and 120 with aluminum bolts but later changed them to steel. Someone will correct me if I'm wrong.
I don't own the 35 either so don't have first hand experience. I have several OS GT33s tho and this engine is the most powerful in the 30 to 40cc class that I Have Played with. Once one learns its idiosyncrasies its an outstanding little mill with really great field manners.
Having said that, you may want to take a look at a thread in Flying Giants someone there compared the DA to the OS. This guys testing seems to favor the DA as more powerful. If true, then the DA has to be a stump puller because the OS already is.
