I'd say order an ego/riva/hello16 now. And make sure to check the supplier forum to see what sales are running when you're ready to order, then check for coupon codes.
If it were me and I was doing it all over, I'd start exactly where I did... an eGo kit and a bunch of random flavors. Shop around, but don't hesitate too long!
I didn't smoke menthol but am loving a menthol juice I just rec'd as a sample - it's got a nice hard TH and big flavor. (Goodprophets.com) I certainly never smoked pina colada, but freedomsmokeusa has an addictive (uh) version that I love. You just never know what's going to float your boat.
I'd definitely recommend RY4 or Wyatt Earp from freedomsmokeusa.com - big, hearty flavor there, and you can get it in 30 or 36mg.
Have fun and good luck!
ETA: Thanks to my eGo I quit the day I rec'd it. I had one drag the 1st night, hated it in comparison, and 26years of almost/at/over a PAD was done. My husband continued to smoke one or two a day for about 4 or 5 days, but now he's quit completely as well.
