The SFNO is the closest match to the SoD. If you lay one on top of the other you can see that they are very close in size. The Camp Tramp rounds out that trio.

If you want to compare apples to apples then the SNFO is your best comparison to the SoD.

SFNO/Tramp/SoD... brothers by another mother. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" /> You can't go wrong with any of them. I would pick them in that exact order of preference. If you price weight your decision then the SoD wins.
