my method.
buy a pac of funky monkey juice cups
cut spam into half inch cubes
take straw from juice pac and using the sharp end push a hole thru the cube of meat, this will leave a nice 2mm hole
add powdered curry or turmeric to your cubes and then seal in a bag
freeze for at least a week till solid
give funkey monkey juice to the kids
keep meat in a coolbag or sumsuch and when you get to the bank you can mount the frozen meat thru the hole previously made, it will cast really well if freelined but will slowly sink as it thaws out, at this point you can either wind in and refresh or leave it to sink while holding the line 'touch ledger' style.
i have found this to be a killer method when all else fails
