Mac it right. Hooks are fine unless you start horsing a big trout or red then I am not sure if any #4 will hold them.
Take you time and let the fish tire out.
Changing the wt out on suspending or slow sink baits will effect the sink rate. Most of the baits are weighted correctly and will sink and about the same rate.
If you look last week I posted back up what the weights were for trebles and split rings in #2, #4, #3 and #5 split rings. Also posted were the wts for the Gamagatsu hooks that some people up use when grass is bad.
The question I have on the corkies is why are you changing the hooks out to begin with esp if you have never fished them much to begin with?
