How about a pony poll this time?

[Beldarna]

Mainsail has been part of my herd for more than 20 years, so of course she's my favorite. I bought her because of the boats and her colourscheme. Close second is Shoreline and I'm happy to have both of them MOC.

[PinkiePosh]

Wave Runner!

Oooh! I thought I would go with Seaflower but seeing them all lined up I am going with Mainsail.

[Katika]

This poll was pretty hard for me!  Based on appearances, I also had a hard time between Seaflower and Sand Digger, but Wave Runner is one of the few ponies that I still have from childhood and the only Sunshine pony I had growing up so I have a fondness for her. I ended up voting for Sand Digger since I just got her like a week ago to complete the set and was pretty stoked about that

[rosierjay]

the only one i owned as a child, and the perfect match for salty is seaflower.
that's the main reason i've never been able to sell her.
wouldn't want salty to be lonely.

I love Sand Digger the best, closely followed by Mainsail.  The rest of the set I'm not too fussed about.

I went sand digger just because of memory of good time taking her to
Indiana beach where dunes are before we moved west long ago
So I got pictures of her there and it just takes me back to when my kids were littler
Ok I'm teary eyed now
Who knew ponies could transport is like this
Ole sand digger!

Sand Digger. She's one of my most wanted ponies.

I like Seaflower.  She aways seemed like such a kind and thoughtful sort of pony. : )

[Loona]

ooooh, I have to let this poll go, I simply can't pick.

Wave Runner is among the few original MLPs I had as a child. I have also found Sand Digger since, and I definitely like her more, but I just can't vote for her over Wave Runner.
I have never seen Seaflower in real life, but she looks very beautiful, she might be the one I like the most (or tied with Sand Digger) from this set.

I absolutely love sand digger's colors, so she is my favorite! I also really like mainsail though

Seaflower <3 My friend had her, and as a kid I always loved her.  Her color scheme/symbols are soooo pretty!

[Ringlets]

I have them all in my herd and I like all of them...   
... but my fave two (because of their colors) are Beachball and Shoreline.  Beachball was my first one of this set and I've had her since I was a kid , so I chose her in the end 

[Rosse]

Seaflower by far! I had her as a kid. I cut her frizzy hair and covered her in nail paint though, haha. Got a mint one when I collected, oh so pretty <3

[Vintergatan]

I voted for Shoreline, although I've actually never seen her in person ^^
