I have never found cheap batteries very good--they always seem to have a short lifespan. I would especially not trust cheap LiIon batteries since they have a propensity to spontaneously combust.
I too prefer a tilt head. I used to have a Gitzo ball head but did not like it and got a Manfrotto monopod head instead which I like.
I shot both RAW and a small jpeg. I can quickly share the jpegs with others without having to convert the raw images. It's convenient at times and takes little extra space. I only load the raw files into Lightroom for editing.
Years ago I dropped an F-1, dented the top plate so that after opening the back the latch would not reengage to keep the back closed. Set it to Canon and they said it was unrepairable; probably out of the part for the now discontinued model. Kept it closed with gaffer's tape until I could take it to an independent repair shop that scavenged the part off of one of their more extensively damaged parts cameras. Used it for many years after that. (Would still be using it if Kodak still made Kodachrome.)
When I wanted color it was Kodachrome and when I didn't it was Ilford FP4 or HP5.
Definitely a type of orchid.
