I have read many times how people complain about that bike that they sold to buy another one.
What I do is to buy the ones I like without selling the previous one, to decide later which one will I sell. That's what I told my wife and now I have 5 bikes and a moped.
What I didn't told her was when did I intend to put them for sale. If she insist, I will ask for an outrageous amount of money so nobody will buy them -or if they buy, that would be a great deal for me-. Believe me, after a couple of months, the ol' lady got used to see the bikes on the garage and won't complain.
Get the SL, live with them for a while and then decide whether you want to get rid of one, both or none.
