They look good! I'd keep the unwrapped time the same and maybe up the wrapped time depending on how much meat is on them and use a bit less wood. If you've got big chunks, it's worth splitting them down into smaller pieces. My last lot were about 3-400g each so I split them into three. One smaller piece usually gives me about an hours worth of smoke, so I use two for most cooks. Also, if the smoker is still going at the end, close the vents down and save the fuel for next time!
