Should I say 'opps'. I made my previous comment before I read all of the comments in the posts. Then, as I backed up through some more of them I saw how you had made the DP9 with your blocks. I really think it is just wonderful. I think it is worth the extra effort for design interest. Someone is going to have a warming treasure. I mull over design choices also and I think the outcome is worth the extra effort. Great job.
