What's the Roadcraft training you're doing?
Sounds the best idea anyway - speak to them & tell them your concerns & they should be able to point you in the right direction as to setting up your bike (e.g. span adjuster) & what to practice.
It's hard to give advice over the internet other than IF your SV brakes are in good condition, then they should be good enough = youjust need to practice, but there could be a mechanical problem.
Only once you are used to the standard brakes in good working condition should you consider any of the available upgrades.
