Love the title you have given yourself :) It's no doubt then that you are following the standard guidelines for tea!
The infuser does hold 18 ounces so you are correct in increasing the amount of tea. If you were using your Wild Strawberry tea, you can safely let this tisane steep a bit longer to extract more flavor without it becoming bitter.
We do offer another infuser that holds less water, and has an infuser strainer basket inside. It is a flask style, so it is perfect for taking your tea with you anywhere and will keep your tea warm up to 12 hours. Take a look at https://tealeavz.com/collections/teaware/products/tea-infuser-bottle-1
Or another alternative is our smaller infuser basket that sits on top of your mug or cup. https://tealeavz.com/collections/teaware/products/tea-infuser-basket-steepware
