RE: decided on the Twist.
Most of my 3D'rs tend to balloon up in landings. I don't see that as a problem, just something to get used to.
The more aft C.G. lends itself to this when coupled with the thicker wing airfoils.
I introduced no down or right thrust on mine. I find it doesn't need it, especially if you stand the tail gear a bit more upright.
I did re-inforce the firewall and gear area on mine, as I would do with any ARF.
I also tend to drop about 2-3oz of thin CA into my planes to harden/reinforce areas that I can reach... this helps IMHO.
My Twist's covering was also a bit wrinkled, but that was cured by 15 minutes with a heat gun and covering mitt.
I can't say that the Twist was any worst or better than other Seagull or Great Plane ARF's I've put together. All of this seems usual for most ARFs.
Gorish: Don't be put off by this, it's what you are already used to!
