You're making things far too complicated. MiRai just made a video for using IWT and I just did complimenting writeup on it in the Newb's boxing guide, starting at the bottom of post 4.

Jamba strobe is not something I'd suggest using. It's great for certain things, but standard combat is not one of them. All you need is a key for IWT, either tied into your spam key or as an individual key.
