Rickmarlin62 thanks for that mate. I didn't consider getting tangled up in rope and losing a fish.

[Beginner Shark Fishing Advive]

Having fished for the majority of my life, I'm only just discovering the fun of boat & LB game fishing. I'm interested in doing some shark fishing off the beach this summer. 
I'm aiming to target small-medium Sharks around 6ft, with a TLD50 50lb mono. I've gathered a few questions I can't really find answers to, and hoping some experienced fishermen can help.

Will 150lb momoi mono leader do the job?
Do you prefer solid wire or stranded flexible cable?
I plan to kayak my baits out. What's the best anchoring option, running weight or a break-away system?
I was thinking of anchoring a crab float in the area I want to fish and have a burley bag hanging off it. Then coming off the crab float - a bit of line tied to a ballon which is looped on to the leader (breakaway) so the bait is suspended and away from crabs.

Roller or runner? Thimbles on the wear points or Flemished eyes? 

 

I appreciated the help - Thomas.
