I hope you enjoy your 45A - I have one and find it a very good compromise in terms of durability, weight and flexibility. My shortest lens is a 65mm which I use with a recessed lens board and this lens does require drop but the 90 doesn't. My longest lens is a 240mm and on my camera that's about as far as I reckon you could go without using a telephoto.
I find the screen pretty dim and that's my only real complaint but it's still better than my old Linhof 6x9 but nowhere near as clear as my ancient wooden half-plate Gandolfi. It's definitely worth buying f/5.6 lenses over f/8 lenses to maximise the light for compositions.
