here in england it is generally easyer 2 get your right knee slider down than your left, due 2 roundabouts. i woz havin problems gettin my left down,until a very helpful policebiker told me i was "tryin 2 run before i could walk". he said "instead of tryin fast left bends",like the ones found in Redditch England, where i had been struggling 4 a while,"find a car park and just keep goin round in a steady 2 slow circle lowering the bike as u go", i promptly did as he said and within 4 hours of practicing i woz back on my way 2 the Redditch Clover Leaf and nailed it first time
