I typically up-size the hooks on all my baits, but I also prefer to go with shorter shanks when doing this on cranks so the overall weight is not affected... I think a larger gap gives the most consistent increase in fish on any given lure (but I agree with WW that the triple grip is a meanest one a fish can tangle with).
With all hooks equally sharp, thinner wire will always penetrate easier than thick in both flesh and bony jaw parts, but the caveat is light line doesn't allow for penetrating those bony parts, which is why I go to a wider gap to help get around them instead.
