never tried peach wood before! if you have never tried smoke lamb, give it a try, it takes on a whole new meaning of "good eats"!
one year i smoked: beef roast, whole chicken, trout, salmon and lamb roast all at the same time and the lamb won hands down. it wasn't the best cut but then again when it comes to smoking, you can take blade steak/roast and make it so tender soft.
way to go on the smoke trout!
