Anyone have experience with peaches on Empyrean 2 rootstock?

Arbor day uses Nemagaurd and ships to zone 5 http://www.arborday.org/trees/treeguide/TreeDetail.cfm?id=70 :Attributes While peach trees are self-fertile and don't require another tree to produce fruit, planting two trees is recommended for a better crop (it will still require insects to pollinate its own flowers). Fruit trees need a minimum of 6-8 hours of sunlight daily and regular water. They are not drought-tolerant. Our standard Belle of Georgia seedlings are budded to Nemaguard rootstock, and our dwarf seedlings are grafted to Prunus besseyi (Sand Cherry)

Mature tree on draft root stock be 3 bushels.

Thank you speedster for the info. My grandparents had a small orchard about 1 acre. It wasn't anything fancy but I loved that place as a kid. After they were too old to tend the trees and farm the hillside just went wild with peach trees everywhere. lol The trees do produce peaches but are only golf ball size and not very good. The trees range in size from large trees to seedlings. My intention is to dig some of them up and move them to a different location. Use them as rootstock for red haven, contender and other good verities. I just didn't want to wast my time if they would not be as productive and vigorous. In my area I have read that lovell rootstock is good for peach trees. would their be much if any benefit to grafting my trees onto lovell verses using the rootstock I already have? I hope to eventually have about a 5 acre orchard.
