Firstly, welcome to the forum.
IME, some folks choose to go straight to CE whilst others prefer to have a few months practice in a C before tackling the larger vehicle. It really is personal choice.
The “cons” are that you will have little experience in the bigger vehicle if you go straight to CE. The “pros” are that you’re still in learning mode and wont have picked up bad habits.
A clever move would be to take advantage of the Black Friday Offer (at the top of the threads). You will have until Christmas next year to complete the training so you can choose either route.
All the best, Pete
