I've never botted yews or magics. But what your saying is two days to make back the bond price is basically 1-1.5m a day, which is less than 100k an hour?
Just run a fletch bot can imagine stringing yews is over 100k an hour? 70 fletch will be quicker than 70 wc also, running 24/7 will make back your bond price
If the acc makes it to 99 fletch, sell account rinse and repeat?
