Those are excellent for surf fishing the Cabo San Lucas area and anywhere along the Pacific shoreline. But those are way overkill for the East Cape. I've fished from the shoreline of Rancho Leonero on many occasions, and caught a dozen species there, but nothing over three pounds. There are many interesting and fun critters to play C&R with like pufferfish and small snappers and bass and needlefish, and sometimes baby roosters. Starting fifty yards offshore you may encounter small dorado and bonito and even schoolie tuna.
Take one of the larger outfits, it will be fun from your panga. But for walking along the sandy & rocky shoreline, a 3000-size spinner with 20# braid and a 10 foot topshot of 12# mono is all you need.
You will have a blast! May I make a couple of suggestions? You will not return until after the lunch service, and it is a long haul until the evening dinner. It costs nothing extra to order double lunches for yourself and anyone else in your panga, and you can offer food to your guide (who probably won't bring any) and then you can bring something back to your room upon your return to snack on before dinner. Take at least two nice gallon Ziplock plastic bags in your backpack, and put a good amount of the ice cubes from the ice chest on the boat into one and then back into the ice chest. At the end of the trip you can scoop any leftover sardinas baits into it, and it will preserve them nicely until you go on your late-afternoon beach walk. I have found that while small flashy lures like Kastmasters work well, nothing beats a fresh-dead sardina cast with a clear casting bubble.
Also, if you get a dinner-sized dorado during your fishing run, if you fillet it and put the cuts into the other gallon Ziplock and into the ice chest, you can give it to the kitchen upon your return, with a smile and a small tip, and they can cook it for you for dinner that night (in addition to whatever they have already planned on.) There is nothing better! I do a lot of C & R, my days of trying to bring back fish from Mexico are long past, but they can take care of that for you if you wish to hassle with it. On the panga, I smile and offer the fish to the pangero "por su familia?" before releasing it. Even though I will tip well, and they know it, it is only polite to ask. Nobody is getting rich down there, they mostly just barely get by. Leaving a few dollars for your maid each day also is appropriate.
Have a great time, take lots of pictures, and post a report on your adventures, please. I'm looking forward to it!
