Hmm... seemed to have had this discussion time and time again. Me... ditched two Stellars; SEI 1G, in Excel and an S18S in Advantage and consolidated on a 2015 SR 2G (Excel). Love the SR and is the perfect boat... for Me.
As red_pepper has stated and has been mentioned many times in the past, you have to take the layup of the boat into consideration when you are deciding on a new / different ski. Yesterday, for example I had a short 10 min paddle on a SEI 1G in Advantage. The handling and stability of this layup compared to my old SEI in Excel was literally chalk and cheese. So much so that if my old SEI was in Advantage layup I would still have it.
Similarly, had a Performance 2G V10S a couple of years ago. Thought it was a bit of a slug. Took an Ultra V10S for a paddle and loved it. Totally different feel and much easier to paddle.
Can understand that this can all be confusing, but believe me the difference in handling and stability in different layups can be an eye opener.
All the best in your deliberations andis.
