Hey @Ben Williams Your question : THIS drive yes, you can do it. While its highly recommended , to invest in these if you plan to be moving up the ladder, and Till FB+ itd not part of mandatory gear( if you go by requirements listed in grading structure of our club) . Once u decide to move up/ apply for promotion to to IM, You do have to provide a confirmation and pictures that you have these gears with you.
Trust this helps:) So for the time being you can postpone the investment , but again, if you drive with other clubs/friends too, this is a recommended gear!
