I have two 09 GTI SEs. I know the body style is different and I don't have a brake, but I saved a kings ransom over new. (they were new but I just got them this year).
I have the 155 and my wife has the 130. She says my ski is much more "jumpy" than hers is. I didn't get the SC models because of maintenance and honestly, I don't have a desire to go 72mph on the water. I'm all about turns and just playing. Also longer journeys so gph was important as well. I absolutely love my ski. Will I trade up in a few years? Prolly.
On that note, SOMEONE PLEASE MAKE A 4 STROKE STAND UP!! Lake Mead is kicking off the 2 strokes and I was about to get one! BOOO! I miss flipping and diving underwater.
