It made the best-looking B&W slides I've ever done, as I remember, when processed with relatively simple reversal chemistry. The extended red is nice, and it's amazing the skies you'll get either without filtration or with simply a #8. 120-sized slides from it would be a sight worth seeing.
OTOH, it's a thin-base, curls like mad, and is sharp enough that it will show you camera shake you didn't think you had. Maybe in the bigger 120 rolls, it won't be so bad, but in 35mm I feel like I'm holding a garter snake while cutting it.
BTW, an alternative to Technidol is X-Tol 1:2, 6 min @68F. The Massive Dev Chart will have the exact time, but I used this recently on an old roll, and the negatives are outstanding.
