Ballistic Batteries
 

OK; maybe this doesn't technically belong in the "Gear Section," but I wasn't real sure where else to put it.
Anyone have any experience with these batteries? I got looking at my trusty old Yuasa I installed in the zx9 in 2003 (still starts great!) and it made me a little nervous. (C'mon, they don't last forever.) I'm not convinced I need a tricky dry cell battery at almost twice the price, unless some of you folks have experience to convince me how wonderful they really are...

Any feedback??
