@emjay - as far as probe placement in the valve goes, would I just be recirculating the mash for the entire 1 hour then to get a constant reading?
Yes, a recirculated mash system should generally circulate for the full hour, or until full conversion if that's what the recipe calls for.
You mentioned in the OP that you don't want to do HERMS or RIMS? My only concern is mash recirc without adding any form of heat input. Recirc is inherently lossy as the wort goes through hoses, pumps, fittings--and loses a lot of heat to a keg MLT.
If you are going to recirculate, you may want to consider RIMS or HERMS. If you don't want to deal with those, a cooler style MLT or very well insulated (and preheated) keg MLT would probably be in order.
