Buckmore is local to me, I'm going there for Junior Rookie Club so I can race the championships
My experience of teams in karting is if you can afford to run in them, then 100% do!
The slight downside of this is the outrageous price tag to run with them! (I've heard horror stories of teams asking for £30,000 as a deposit to show your interest.
At the moment I run Junior Rotax with just me and my dad and we finished P5 in the last race at Buckmore against some Super One guys but damn its hard work! Our season budget can't be much more than £3,500 a year and apparently, most of the Super One guys spend somewhere around £100,000 a year...
Best of luck in Junior Club! (It's where I started!)
