Thanks for the recommendations. I'll draw what I can from the feedback and pick a starting point.
Some thoughts so far based on what I've read:
- most of the time I'm aiming for 3 x 150ml cups, based on my gaiwan/cup, and time available (this is the type of tea I would have after dinner, and I don't usually have enough time for many more sessions nor do I want to stay awake all night)
- so I tend to use less leaf to water, and brew for longer, so I may try 5g for 150ml water, and steep for 2 minutes (increasing time/temp from there)
- I know with gongfu style brewing the idea is more leaf to water and shorter brew times (resulting in more infusions), but for reasons above plus cost, I will only do this from time-to-time (weekends, working from home)
- I've moved towards sencha recently as it's what I like best, but I do want to keep some oolong in the mix
