Thanks for the heads up on EM Champion. I'll have to give it a try this next year.
For those wondering like me. Here's a description from Tatiana's (and a good source to get seeds!):
"Sprawling determinate plants with wispy regular leaf foliage grow up to 3' tall and are excellent for growing in pots. High yield of red fruits, from perfectly shaped hearts to slightly ribbed/ruffled. 6-12 oz. Delicious balanced flavor, meaty flesh. Very few seeds make it a real challenge to collect save many seeds for this variety. (15 seeds / packet)"
Here's a T'ville link where it was discussed:

Thanks St. James!
