Aroma Tabs? Cool or not worth the time?

[boussh]

After attending a great IPA fest at the Bistro in Hayward this last weekend, i heard rumors of these crazy little hop aroma tabs being used in several of the beers. Curious, I called our freinds at hop union and they told me that they had them, but didnt give too much detail on thier usage. I ordered the "generic aroma" (i guess they are phasing out the Cascade as no one likes them) tabs and plan to do some experimenting, but was wondering who else is using them and how they have helped or hurt your beers. Any suggestions on usage?

Cheers and beers
