Stripers (we call 'em Rockfish around here) are hard to mess up. I'd recommend against smoking them as the meat has a very subtle, delicate sweetness that I'd hate to overpower. It would probably taste really good, it just might taste more like smoke than rockfish. Grilled is good, as is fried, sauteed or broiled. A little salt and pepper and maybe a splash of lemon is all I like on them.
By the way, if you happen to find yourself fishing for blues again, bring them home and smoke them. A night in a salt/sugar cure folowed by a few hours in a relatively cool smoker and you've got some serious good eating. Served with lemon and capers as an appetizer it's AWESOME.
