My local shop has one of these, and it is really a great commuter bike. Not only does it have a better geometry for longer commutes, but it comes with fenders and a rack which both make for a better commuting experience. If your shop doesn't have one, they may be willing to order one for you.

I have done my 27 mile r/t commute on an upright hybrid with suspension fork, and know it is doable. I now do it on a different bike with less upright geometry (and a rigid fork) and find the commute to be less work, especially when climbing hills or in wind.

If you feel you really need a Cypress, I would get the ST. I've tried the Cypress and the Cypress ST, and believe you won't feel that the ST is heavier. The rigid fork will be nicer for long commutes, especially when you need to hammer it to get through an intersection.
