westcoast is where I fish.
Post up pics of your winch bludog,and ill give you a few pointers on fail points (if any) as I did on my first go making one.
Dont bother fishing on or just after a full moon on the west side,sharks galore.
If you want to do it solo,bottom LL is the easiest,and you just clip on as it goes out and unclip as it comes back to the winch,best use a supplimental skyhook kite to help drag all the line out.
Its all a big balance act from the bottle back ive found.
I wouldnt fish anywhere with any sort of rock/scrag,as you will get snagged eventually.Even on sand beaches you will have trouble,with sand bars and submerged trees and the like.
I usually set the kite up,with my dropper on the spool lying next to me with a spike thru the middle to hold it on the beach,bait up the traces,let it out a few meters to wait for the bottle weight to load up,adjust and then let the kite out and put traces on at it comes off the dropper spool.Keeping the mainline free of the water is the most important part,as the rips will pull your line along the beach and shorten the distance from shore,the only upside is you cover more fishing ground
