I use both types of snakes with and without the swivel,alldepends on the mood i'm in,,(but i'd still rather use a tube than a snake),,the only time i use shrink tube on a snake is when i do glow snakes and it aids protect the glow powder on the body,also i only use 20lb masterline braid(after all your doubling everything up anyway)and to break 20lb on a fly rod takes some doing...
both mounts..
shrink tube cover...
a quick charge..
also if you use a swivel and shrink tube you can tie a easy snake with carp braid(kryston type)if you black the braid with a black marker it acts as a lateral line on the fly..
braidy snake..
some 'dark knights'
elver snake..
anything you can do with a snake you can do with a tube(and tubes are easier to tie!!!!
specially made snake vice helps...
when tying snakes for second half work close to the bottom,tie the snake using a double as it swims upside down most of the time,thus avoiding lots of snagging up...
