Even for "slicing," I like tomatoes that are very meaty, with small seed cavities, and I generally stick with OP/heirloom varieties. German Pink, Potato Top, Amish Paste (really an oxheart), Mr. Stripey (bicolor yellow/red) are larger varieties that have performed really well for me. Wisconsin 55 is a reliable producer of red, smoothly round "normal looking" tomatoes, a little smaller than the others but still 10-12 oz (not a saladette or cherry type). Summers here are probably a little hotter than for you. I do have to spray most years for fungal issues (early blight, late blight), given high humidity.
