Using the above stats, i managed to whittle the 40-strong field down to 17 (who scored 10/11 r 9/11) and a second sweep with the scythe (using other stats and certain form guides) brought that number down to about 7 or 8. Of those, i have settled on the following 3 (all Irish-bred);
Night In Milan @ 25/1 - scored 10/11 - failed on having contested more than 16 handicap chases. Sole run at Aintree was a one length 2/14 in a 3m 1f handicap chase. My idea of the winner, therefore my main bet.
Alverado @ 22/1 - scored 9/11 - only had one run since Sep and unplaced lto but, as explained above, Paul Maloney rides this course better than most.
Oscar Time @ 40/1 - scored 10/11 - unplaced lto (at 14 yo is probably too old to win the race but it did have almost a year off and has been placed in 2 previous Nationals. The added bonus is that Sam Whaley-Cohen is the most successful jockey to have ridden over these fences and that, for me, is reason enough to part with a couple of quid e.w.
That's me sorted, once again, best of luck.
