Depends on your personal riding situation. My first 570 had none, so I was constantly tapping the gas on long descents to keep it engaged, otherwise it would freewheel and I would be riding the brakes downhill from 8 or 9000 feet down to 5000 at the trailhead. Good in the mountains, bad in the dunes, sometimes bad in the snow. Many complained about the 2013 570 in comparison, said it threw them forward into the seat belt when taking foot off gas quickly. Read a few threads about EBS, you'll quickly find that it's a love//hate relationship. A third love it, a third hate it, the rest don't mind either way. I wish I had it, but I don't ride dunes or snowy trails. Wife's Sportsman has it, I had it installed on my old 450 Sportsman, we both like it.
You can check with Hunterworks.com for ways to increase or decrease the amount of EBS you have, but will involve new pieces in the clutches or new clutches.
