My spouse and I are very close to buying a daVinci, with S&S couplers. The appeal is the ICS, independent coasting system. On the surface this sounds like a swell concept. We have test ridden a daVinci once, and a number of other typical tandems. Our tandem riding intentions are simple touring, maybe a social century. No racing. Hills, but no mountain climbs.
Is ICS a drug? Is it a crutch? Is it the lazy way?
Does it detract from smooth power flow to the cogs (wheels) when the cranks are out of synch?
Does it make it easier for either rider to slough off their part in applying power (doing work)?
Is ICS just one more thing to deal with when packing/unpacking, and is it just one more item that can malfunction?
If it is a good concept, why so few daVincis in the ownership polls?
The captain is a road and mtb racer who will have to learn to relax and go for a nice ride.
The stoker is happy to lay back and view the scenery.
Thanks for your input.
