Most people I know who race say the Q2's are slick when cold/new. Of course, that's true of most any tire probably also.
I'm going to keep the Q2's and maybe run them on the track. For the street, I'm installing Pirelli Supercorsa SP's and going to give those a try. I think the SP's are probably better tires than the Q2. The Q2's are good tires for the money for sure, but I don't think they are in the same ball park as the higher end Pirellis.
Time will tell.
The 190/55 Q2's are 200mm wide, while the Supercorsa Sp's are more like 188 as I recall (I think they are 193 on the rims, but I'll double check when I mount them).
In my specific crash, it was because the tires were not fully scrubbed in, it was cold and I had the pressure too high probably (35/35 when I probably should have been running more like 30/30 maybe for the temp).
The main issue is a dip in the road at the apex. I'm not the first person who has had problems on this particular corner. However, I had come around that same corner many times on the Corsa III's and stepped out the back end with no problem.
You say you put Q2's on and had no problem first lap. But I know someone who did that and low sided on the first corner also...
Talk to 10 people, you'll get 10 different opinions.
Q2's are a lot of bang for the buck. Myself, personally, I like the feedback from the Pirelli tires a bit more I think. I might try the Q2's at a lower PSI and see how they do, but replacing body work ain't cheap :-)
