I was in the same position last year. I had initially planned on getting a 125 and using that for 6 months but that went out of the window as soon as I did my CBT. I found I got bored of the speed, or lack thereof, very quickly.
Did my CBT then the following month I booked my Theory and then cracked on with my direct access (I had to do mine over a few months due to work commitments). I think I had CBT > Theory > 2 x Mod 1 Training > Mod 1 test > 2 x Mod 2 training > Mod 2 test.
Passed it all first time and now I own a R6. In hindsight I think I could've got by with just 1 day mod 1/2 training - so depending how you get one you may find 1 day training ample enough
