I am a heavy-hand writer.

The frame is light and easy to hold.
All along I’ve used 0.5 mechanical pencils.
But now I’ve switched to 0.7.
And back again to 0.9.
It is my first time buying 0.7 mechanical pencil and for me I gotta say it feels awesome and comfortable at writing 0.7 than 0.5.
It is really better choosing mechanical pencils where you can feel comfortable using.
