We only saw two spiny and got them both. One was on the way in, I was only about 2 feet off the reef and one was walking right under me. Scooped that one right up. I ended up putting in Shane's catch bag, had some troubles getting mine open. I ended up loosing my bag with the hog I netted shortly after.
The simplest no fuss way that I like is to butterfly the tails, put a little salt and pepper if desired on them, make a garlic butter with fresh garlic and fresh cilantro. Baste the tails, set grill to high. Grill face down (fleshy side) for one minute, flip and grill on shell side for about 9 minutes on indirect heat. Baste the tails a couple more times while on the grill. You can do about 7 on direct, but the bottom of the shell gets burned and it get's messy.
Take some kitchen shears and cut off the tail and the frilly things on the underside... The rest of the shell wont burn...
