Vibration ideasI have used the TT Wood blades for several years and no real vibration problem. Do make sure there is a little lube on the rubber dampers for the spindle shaft. Can get sticky with age, but a drop of lube or fuel should take care of that. I also make sure the tail blades are sort of lose, not sloppy lose put able to move in the grips.
Now the big question. When you are done flying, do you fold the mail blades back and put them in a foam blade holder arrangement. If so
pick one ball link on the main blade grips and pop-it off when stored. Reconnect next time you go fly. I would get my blades in track and all would be good and then fold them back and the next time out they would go out of track again. Finally an experienced FAI pilot told me to try popping one link and taking the stress off the linkages when the blades were folded back. Anyway, end of tracking problems. Also with warm and cold weather season here, take your heatgun on low and go back and reshrink the covering on the TT Woodies and you will see it shrink down nice and smooth, but just go slow and on low heat. You will like the Maverick 680's for your TT70 combo.
