Richard nodded at the offer of an actual quill. Thing was, even with an Everfilled Quill spell, the things couldn't keep up with him. He'd accept the thing in the spirit with which it was offered, and keep it with his other antiques.
"Keep the journal; I picked it up for you to document your research."
"Oh," he shook his head and laughed. "I've blown up more than one broom on the pitch. It is easy enough to do playing Seeker. High enough, you throw a Featherfall and bail. Too close to the ground, you look for a soft spot to hit and roll, grab your number two from your rack, and get back in the air."
"Here's the thing," he continued, "everything you do to a broom affects every other thing. Once you have a handle on how everything works together, you can patch individual bits without changing your setup. Setting your broom up in the first place with a single enchantment, working out the Arithmancy of how everything interrelates, means you do your bodging ahead of time, only alter one small aspect, and document what should happen as opposed to what actually happens. If you flip to the pages at the back of that journal, you'll find an equation marked, 'Wipe', ones for 'Every Day. 'Short Track,' 'Cross Country,' and one marked 'Quidditch,' which is to the standards of the professional rule book from my time. All setups for my flying style on brooms I build. Fill in the space between the one I wrote today and those with your own, and when you feel confident enough, start your own journal with only your own work."
He glanced at Arcturus' plate. "No rush, we have all afternoon. When you are finished, would you care to do a little flying?"
