I loved my Bilenky. But that's a bucket of its own issues. Cons:

• Bilenky. The timeline on the build was originally stated at 3 months; it was delivered 14 months later. Fine, whatever. The stoker boom was welded ~1 degree off-center. That's the kind of thing nobody would notice. The person to whom I sold could barely notice it even after I pointed it out, but it stuck in my craw.
• The price. My Viewpoint was $11,000USD in 2014. I sold it for $8000 and the buyer didn't even balk. They drove from Minnesota to Washington to buy it because price and timeline.
• The midship rack. When I bought my Viewpoint, Haulin' Collin was the only person making the midship rack and center kickstand. He's a custom bike fab shop in Seattle. The price and timelines are what one would expect for custom. But his work is impeccable.
• It's huge. But you don't buy any tandem if you live in a small apartment. You need a place to keep this. It was still slightly shorter than my diamond tandem though.

Pros:

• Bilenky. The design of the Viewpoint is well-trod and tightly refined, having been pioneered in the Counterpoint Opus. Bilenky's version is dialed.
• Their paint! OMG, their paint is easily one of the best I experienced.
• Generic parts selection. Whatever you want, you can get it spec'd. Want to change something? No problem.
• Independent stoker drivetrain. The stoker can select their own cadence. Unless one is an experienced tandem captain, one might not think this is a that big of a deal. Absolutely buy this option.
• S&S Couplers. If you go with this option, the bike fits into two airline-standard cases. Although it took me two hours to pack it up. And it does limit your component selections a bit.
• Generic recumbent seat. If your stoker wants different ergo, it's easily accommodated.
• Generic two-legged kickstands work just fine for the bike, but you won't be sitting on the seat with one of those.
• Rides great solo. This applies to all semi-recumbents. Riding a diamond tandem solo can be risky; the rear wheel wants to slide out in turns.

Another bit on the Hase Pino: if riding solo and without cargo on the front, the front wheel tends to wash out. No bueno. It's cornering capabilities are a scant fraction of the Viewpoint.
