Ed -- I would have never found your wiper perch topic if it would not have been for Dave Willis' post. I do not monitor the Pond Construction topic very closely.
We have used the wiper-perch combination with pellet feeding in several smaller ponds (0.3-0.7 ac) in NW Ohio. Currently,,, these ponds are only around three years old. So far,,,, things are doing fine. Good growth from both species. No evidence of overabundant perch. In fact we have several small ponds with only perch stocked and,,, with good management, no perch stunting has occurred when they are fed pellets. Not all perch will pellet train and those are thinned out when caught.
The main draw back(???) if any, to this combination is lack of wiper reproduction which might lead to an overabundance of yellow perch.; esp in weedy habitats. If you closely monitor the sizes of perch you should not have problems. As overabundant or stunting of perch begins to appear implement thinning; fishing, trapping, seining, and/or adding more wipers. A combination of some of these methods could quickly thin hundreds to a few thousand crowded perch. Overabundant perch numbers, could be manually thinned or reduced by adding more wipers. Our exerience is that large perch (10"- 13"+) will do some or a fair amount of thinning of smaller perch in addition to what the wipers eat. Use selective harvest or slot limits.
I would not be afraid to try this combination because if you decide it is not for your "tastes" you can always at a later time introduce an additional predator species to "thin" excessive numbers of smaller perch. Only a few bass can have a very big impact of dramatically reducing numbers of small (3"-4") or medium 5"-7") perch. Problem with bass is that good annual reproduction can quickly lead to a decimated perch population due to over predation of slender bodied perch.
You should be able to handle the job of adequately reducing the numbers of large 9"-14" perch. If you ever need help with this call me; I enjoy this job!!.
