Right now my almost 5.5 yr old DD is in a FYTF FF at 43" and 35lbs. My almost 3.5 yr old DS is in a FYTFP FF at 36" and 28lbs. I am pregnant and due in Sept and the baby will be in our Chicco KeyFit 30 for the first 9 months or so. At that time I want to put the baby in the TFP and DS in DD's TF and buy a new seat for DD, she'll be 6.5. My kids are really light, we drive a 2004 Sienna so have plenty of room and we do move our seats around a lot so easy install is important (love the True Fits for that!). I'm guessing DD will be in the seat for about a year and a half or two before the TF expires and at that time I'm guessing I'll put her in just a booster and put DS in her combo. We do longer drives since we live in a rural area and she still falls asleep in the car once in a while so I definitely want her in a 5 point. I'd prefer a narrower seat in case we need the back seats for my sisters but it isn't a must. Price isn't a huge issue as long as I love the seat.
