“Don’t use your front brake”??
You need to use a fair bit of front brake (and the rear) on steps around Hebden IME. You need to go down as slow as possible on some sets because of no run-out or sudden tight turn at the bottom etc.
Don’t hang off the back of your saddle too much. Locked arms are of no use. Get low but more central on your bike. Elbows bent.
And yes, start easy/small/regular and go from there :-)
