Aktive reeds have been around for almost 10 yrs here. I wourked with them when I was 15 at the local shop i used to work for. They are pretty nice reeds. I haven't got to use them any of my dirt bikes but really liked them when i had my trx 250r Honda. I been meaning to grab another set just to throw on my bike and see how they respond. From what i remember they were worth the money, you can normally get them pretty cheap. I cant say how they compare to boyesen since I have used them in a while, but I would imagine they are still good.
