I have replaced my Gen1 blades om my MTO Sport with Gyrotech blades, hub bar and head. Done about 15 hrs on them. My experience to now is as follows. Heavier to handle on the ground. No difference in flight. Climbs a lot better. Landings are easier because they hold their energy longer. Takeoff roll seems a little longer when two up. Able to do same air speed. More stable in thermic and windy conditions.
Have some stick shake issues but I am confident we will sort them out. Changing rod end bearings on the control arms and then will start making adjustments.
Replaced my rod end bearings and did some more
Have just abourt zero stick shake. Now feeling a little bit of cabin hop in my back side. As it gets better i am more an more impressed with the blades. Find myself getting very close to VNE whilst flying in smooth air. Will check the tracking again later this month and maybe add a shim if i see something.
Being in the market for a new rotor I believe I have two options, Auto-Gyro Type 2 (or maybe 3) or Gyro-Tech with teeter tower.
I have a 2007/8 MT-03, which was converted early on to a MTO Sport by factory people - but it still has a Type 1 rotor and head.
Besides ordering rotor and teeter tower, did you do anything else? Specify holes for gear or bolt?
