I quite liked Forest Affair and Quintessence from T-Juice. Not enough to keep buying/making them, but they were both true one shots - no need to add anything and both well balanced. Their Jack The Ripple is quite nice but the raspberry fades all too quickly and it becomes bland. Red Astaire is excellent, but I sickened myself on it. Green Steam, now that's a poor one from them, to my tastes at least. The main problem with their concentrates are that they are too expensive for requiring to be mixed at 20%.
