Why the Hejnar adapter? I prefer the Arca-style plate and clamp system to the Manfrotto system. That's all. At the time that I purchased my first tripod and used head (the Manfrotto geared head), I started using the Manfrotto plates and they were loose. Furthermore, photographing in portrait orientation was a PITA. I saw another photographer's Arca-style camera L bracket and decided that an L bracket was the way to go, center of gravity of camera stays over head instead of off to the side of the head. Manfrotto didn't have a good L bracket for their plate (they have one now). Through fora, I found out about the Hejnar conversion kit for this 410 head. I installed it and bought an Arca-style L bracket which stays on the camera full time.
I love tripods.
There's nothing wrong with taking a "sketch" photo where the composition is what you want but the light doesn't happen to be right. It is a good reminder to try again when the light is better. I have a bunch of shots in the "try again" file, most taken on a first visit to a location. I drive 2 hours and hike an hour to get there, skies looking promisingly stormy all the while, and then the clouds change to flat overcast...meh.
