Japanese Oxheart - Have you grown it?

[timcunningham]

When I purchased my Momotoro seeds this year, I also bought Japanese Oxheart to fill out my minimum order. Has anyone else grown this? What was your experience?

So far I have several branches with huge clusters of medium sized oxheart shaped tomotoes. One branch has about 10 all clustered together. Seems quite vigorous and is taking over the homemade earthbox it shares with Siberian tomato.
