I recently upgraded to 1617 and over all am satisfied with it's performance. Surf speed isn't an issue with 2 1100s, stock ski locker, and 550 ibs along with 400# lead in the front. Wakeboard speed is another story, still takes awhile to get on plane but it's not too much off any issue because I rarely fill the rear bags 100% (near the point of dimensioning returns in wake size). I don't go above 32 for the occasional slalom set so I don't worry about losing some top end speed.
