I appreciate the websites and recommendations in everyone's responses. These are all good sources.

If I can find another cruiser in a trash pile or a "next to free" one that I can use for beach rides I then may go a different direction with the Isla Vista. After a complete teardown and rebuild of the hubs, headset and bottom bracket everything is super smooth. Without breaking the bank I'd like to change out some of the heavier components for lighter ones and end up with a moderately lightweight cruiser. I use the term moderate because I want to retain the cruiser styling and not spend large sums of money.

Squid, thanks for your cruiser tires comparison in another thread. That kind of info is very helpful.
