I am purely doing this for exercise for now, but might get into some Tris down the road.

For you swimmers out there, any recommendations on goggles. I just grabbed some Speedo Hydrospex -2 at work, because I heard they are very comfortable, but I guess I shouldn't have purchased smoke lenses if I am most likely just staying indoors, doing laps.

Also, some have talked about the book Total Immersion to get a smooth stroke going. Any other books or helpful tips for a newby?

Thanks
