Knock House best of the 100-1 or bigger outsiders

Has some fairly decent big field handicap form. Stayed on well despite being badly hampered from very poor position last time out when 4th at Cheltenham. Jumping not brilliant but with fences not as formidable as they used to be could get away with it. Only 7 and open to improvement and longer distance could well help. Needs 2 to come out. on at 100-1 6 places topped up 100-1 5 places today
