Puffco Pivot vs Dtv5

I've had a Dtv4 for close to three years now. I love the thing but the ceramic spacers and heater wires always seem to be snapping and cracking and I don't really want to buy more. I'm looking for a device that has a bit more ruggedness and pocketability but the fact that I already have a mod battery for thr dtv5 makes me question whether the extra 60 would be worth it for a device that doesn't have a swappable battery like the pivot. Will the pivot be enough coming from the dtv4 or will the v5s new bowl design be rugged enough for me to not question bringing it out of the house or letting my friends use? Also for those that have both, what are the major differences in experience?
