Hi Mozi,
14lb braid is fine in my opinion, although some guys go as high as 40lb - I really think this is overkill. The general recommendation is no less than 14lb braid on baitcasters, and I think this may actually have more to do with the diameter than the breaking strain - if too fine diameter, you may tangle easier and tangles on finer braid are more difficult to undo. This can be frustrating and ruin an entire trip, so if you are not completely comfortable with your baitcaster, rather go with say 20 to 30lb braid. Also, the first strike of a tiger is usually explosive, so if you have poor quality braid or bad knots, say bye-bye. Make sure you get a good quality braid. I use the palomar knot for braid to my swivel, which has not failed me yet.
On the rod you have, obviously a different model to what I have and sounds ideal for the job. Might check out one like that for myself netx time I'm in town.
Re the clips and lures (in the dam): I started out trying every lure I could find, but eventually found that many of them could raise the strikes, but few kept the big fish on as wells as a spinner with a big single hook. So now I only use the tigerwakka spinner. I might change colour and sizes during the day, but try to do this as seldom as possible. Tiger feeding frenzies are short and quick and you don't want to be caught changing lures when three of your buddies go vas with dream fish all at once, and you miss the opportunity. The key is to find something that works (ask the locals) and stick with it - spend more time working the water than changing lures.
Because I started out trying so many different lures I also used a clip at first - there are some seriously strong clips available that I have also used offshore so I have no fear of these breaking. Many guys also say small tigers may bite you off at the clip, but I have luckily not yet had this experience. But nowdays since I change lures less often, I really have no need for a clip. And this lessens he chance of getting bitten off by rats and mice anyway.
A word of advice, if you do intend to use clips, find the smallest strongest double lock snap you can get and tie this onto your mainline / braid. Then do up all your lures / spinners with say 1 foot of steel trace and a power swivel, prepared before hand. When you're on the water, simply change the lure and trace at the mainline clip. Traces often get kinked after a fish is hooked, and this is where the clip may come in handy. But still, these days I prefer to do it without the clip.
BTW, never use a clip right at your lure. if you hook a fish, it could unlock your clip with its biting action, so if you are going to use a clip use it on your mainline, about 30cm away from your lure, seperated by your bite trace.
Just my 2 cents worth, cheers.
