You can check wif kokomo, she got her 2A a few mths ago, riding
S4 very soon, right...kokomo???

My personal experience, ........ i stop my 2A at prac 3, that was
last year, now dun feel like taking at the moment. My 2A was taken
at SSDC, weight wise, confirm heavier that 2B, but with some
practise and on the move, no problem la. The rest like S/crank
course same as 2B lor.....
