Before you randomly make a lot of changes, get you bike running satisfactorily.
Running on "choke only" usually indicates clogged pilot jet/pilot jet passageways.
If the pilot jet/passageways are completely blocked, Seaform won't help. You need at least a minimal flow through the jet for it to work.
The pilot jet/passageways need to be manually cleaned by soaking or using an ultrasonic cleaner.
There probably isn't one carb setting that will take you from sea level to 11,000 feet. You should tune the TW for where you do most of your riding.
