BA speed
One thing that might help. The 350 is a little harder to tell if you are in trim, if you are coming from a robbie. Two things can throw you off.
The trim string out on the little flag pole makes it hard to know if you are exactly in trim. The second really is because the 350 can be loaded with a large variety of lateral CG, so to be truly in trim you may feel like you are leaning, the ball will be off. Just a little out of trim can easily steal 5-8 knots, without you really even being aware.
