Welcome to the forum.
What kind of issues on your old Cannondale? If you really like the bike and it's doing a good job for you, repairing is usually cost effective unless it's a frame issue.
I totally agree with what Sheila says about the old step through frame. That's a very old and outdated design dating back to the days when women wore skirts while they rode. Very poor choice for any distance riding.
I'd also try to find a bike with at least a 9 speed gear cluster or, even better a 10 or 11. Those old 8 speed gear cluster bikes are already outdated. Parts and servicing will be limited. I'm surprised anyone is still selling bikes with them.
That Troll is a good choice. As close as you can get to a do everything bike. It's a bombproof bike with good components and that frame would last you forever. Those 2.5" tires and steel frame would do more for riding comfort than those cheap front suspension forks usually found on these hybrids. Another big plus is the gearing to handle any hill you might encounter and should you decide to go off pavement, you'd also have appropriate gearing. I have that same handlebar on one of my bikes and love it. Lots of hand positions. Very comfy to use. More expensive, bike, of course, but it won't be falling apart on you in a few years.
