I don't have nearly the experience, but I second what DE727UPS and Doug said.
I started at SkyW with about 1900 hours TT. I felt like I could nearly always have a nice landing, maybe not always a greaser, but a nice landing in most GA aircraft that I flew.
I now have a 1000 hours in the EMB 120 and I can always land the thing safely, but I'll be darned if I can always grease it. If it is light then it is super hard to grease. I will have really smooth landings for a month and then the next month they will be just OK or occasionally even elicit a laugh from the Capt. (Of course then they go through the same thing, so that makes me feel better in an evil way.)
Then again, half the time it is gusty or I am five miles behind Doug or one of his constituents flying the glide slope just a little high to avoid the wake. Or if we are lucky we land just after a 767 or 777 has rotated so we are trying to land in the remnants of the jet wash. That can be exciting.
mrivc211, The other day I landed in SUN. Really light airplane with flaps 45. Ref was like 103 or something way lower than I was used to. Had to triple check the fast slow indicator to assure myself that we were not going to fall out of the sky.
