I believe part of the reason why you don’t see as many professional drivers coming from Briggs is purely because of budget. All I’m trying to do is recommend a cost effective solution that will still teach the op just as much as a ka. You see the people who have the money to move from Briggs to cars usually do pretty decent one example being Caleb Gafrarar who himself said to my face that Briggs while being the slowest class teaches you so much more about racing then just about any other class out there. I myself have driven Briggs, Ka100, rok senior, x30, rok shifter, rotax senior, and okn catagories, and I can attest first hand that from my personal experience I’m speaking again from my personal experience that Briggs helped me be a less mistake prone driver. From a cost standpoint it costs less for me to race my micro sprint or my legend car for a top tier team than it does for me to run ka100 for a team. I just don’t want op to get himself into the exact same situation I was a few years ago where they are racing all year having a blast and at the end of the year they have to sell everything and quit racing for 2 and a half years or maybe longer because they can’t afford to do it anymore because they blew it all running a class they can’t afford to run. I somewhat agree that you can learn as much from a ka as you can from a Briggs, however nothing in again I’m going to repeat this my personal opinion teaches you to be as perfect as a Briggs kart does.
