I have the tape in question. It's tough to review, since it's not focused on a single scene or ticklee -- I suspect Harmony found themselves with a bunch of snippets and outtakes on their hands and said, "Hey, let's make these into a video!"
For instance, there are two scenes where Ariele Cole gets tickled, but together they add up to less than five minutes of screen time -- it's hard to imagine why they'd hire her to appear and then use her so briefly. Similarly, in the middle of the tape they drop in a scene with Kristine Imboch being tickled, which is again oddly truncated.
The scene where Ashley gets tickled five-on-one takes up the last ten minutes or so of the tape. Ashley is also tickled one-on-one at the beginning of the tape, and she tickles Laci Diamond in two scenes that round out the rest of the video.
As for the quality of the tickling: definitely more intense than the gentler tickling of later Harmony. Ashley's first scene is nothing outstanding, but the five-on-one scene she's getting tickled hard. She doesn't move much, but the guys tickling her aren't going easy on her -- they look like they're trying to dig through her skin (a bit of a turn-off for me). If she's faking her reactions, then she's a damn good faker.
Imboch's scene is also good -- no surprise there -- as she's tightly bound and has a wonderful look of agonized pleasure on her face as she's tickled. Ariele is worked on too briefly to really rate, but I'm a sucker for her giggling. Laci's cute, but Ashley isn't an especially vicious tickler, and lets her squirm too much and rest too long between tickles.
Overall? I like it, but then I have a weakness for early Harmony. If you want it just for the five-on-one scene, then you're going to have to balance those ten minutes against the rest of the video, which you may or may not like.
