i agree with the other posters, don't plan on doing the get on subpar, bail, get on somewhere else thing, especially where you are right now in yoru career, by the time you've got your instructor ratings and a little more flight time, who knows what the industry is going to be doing.

I had a few friends who did their commercial x-countries in twins, which if you can afford it is definately not a bad idea. Especially when you consider you'll have to go a little bit further to get the same amount of time, which will allow you to get some realistic (storm dodging) weather in, probably some IFR, all of which will only help you when you get to the regionals. It's nice to plan ahead bud, but you've got plenty of time, so don't get ahead of yourself.
