hyperbike

Hi all! I have a cart dilemma, and any input would be appreciated! So, my parents are generously offering their semi-broke newlywed daughter two wonderful Christmas present options...either a Hyperbike, or a new (less expensive) easy entry cart and a new harness. I’m having a lot of trouble...

I'm very new here, and I'm more into showing, but I noticed many people were looking for a whip suitable for use with a Hyperbike. We use these whips for in hand showing with bigger horses in the UK and was wondering if it is a good solution to the problem as it is short but has the lash on it?
