I'm sure you know that Oregon Spring is a parthenocarpic variety, which means fertilization by pollen is bypassed and fruits develop abnormally with regard to the normal process.

If you have to grow parthenocarpic varieties because your temps are too low to allow for normal pollenization, then that's OK.

But parthenocarpic varieties can be mushy as well as malformed because of the way they have to develop. Size can also be all over the place and I would imagine growing in a hoop house might also influence that in ways that I can't specify since I don't grow my tomatoes that way.

Rather than disbud and prune, which can increase fruit size according to some, and not according to others, I'd switch varieties first unless you absolutely have to have varieties that set fruits easier with cool temps becasue they are parthenocarpic.

There are plenty of round red, blemish free, high yielding varieties that could sub for Oregon Spring if parthenocarpy is not the issue here.
