Good job. The temp profile will really help and it would be good to take it for a full year through (esp. winter temps). On YP see pages 20 -21 of Bruce's thread :

Same upper range as YP 30C or 86F.

I assume you are sure you will not have a DO problem in summer without aeration. That is not really the depth/temp. question you ask so I am not addressing that (thermocline) with this post. It seems to me that depth may be the question in winter not summer as both species due well much further north and south of you in both summer and winter as long as enough depth during winter freeze over. The winter question would be true also for the BG and RES. I would think that if the BG did ok in winter in your small pond (assuming same depth) I would think the YP and SMB and BG would do ok in your large pond. There are some very good threads here on ice over in small ponds wrt snow removal and keeping a hole in the ice ( for DO purposes).
