All really good tips given... I have close to 2000 hours on 1900's and also very much favour trimming her back a little whilst rounding out.
They are really tricky to land nicely when they are light, as they tend to float a heck of a lot compared to when they are at MLW and a nice rear C of G.
Rather forget about greasing your landings for now, and focus rather on flying a nice accurate approach, on your speeds and nice firm touch downs. I've been bitten more than a few times landing on a very wet tar runway in a crosswind, and not been firm enough with the landing.
Enjoy the 1900, lots of fun to fly!
