I wrestled with this also when buying my first glass ski.
I was very fit from coming from Triathlon and also didnt want to waste time with a ski that I thought I would upgrade in no time.
I paddled both ski's one after the other in an estuary with about a 1 foot chop and 15-20 knot winds.
What I found was that despite at the time having a shocking paddle stroke I could put the power down on the sport but with the V10 I was checking or using a bracing stroke about every 20 strokes.
I erred on the side of caution and went for the sport and I am so glad I did.
I was able to get out into the ocean and really get stuck into training and enjoy the boat.
I am now in a V10L and without the 15 months? I had in the Sport I would have really struggled with going out into any rough stuff (big swell and chop), as it is I am only just starting to keep it upright on longer paddles in rough stuff.
I was able to really develop a good paddling style in the sport with some coaching and the stability of the boat allowed me to focus on technique while I was being coached. If I was in the V10 at that stage I wouldnt have been able to really put those coaching tips in place as well.
The other point I'll make is that the sport is such a popular boat for beginners and novice paddlers who use them for 1 - 2 years on thier way to faster ski's (and in some cases keep them as a 2nd boat for rough conditions) they sell themselves when it comes time to trade up with very little lost in the changeover.
So it's a no brainer for mine, you have very little to lose and a lot to gain by getting stuck into the sport and trading up when you are paddling the sport at it's and your limits.

looking forward to hearing about you choice and how you go with whichever boat you buy
