Which name do you prefer with middle name [name]Hayes[/name] and to go with twin brother [name]Kellan[/name] [name]Scott[/name]?
[name]Spencer[/name] [name]Hayes[/name]. Hands down.
[name]Sawyer[/name] [name]Hayes[/name] has the repeating y’s and the w which I thought were super cool when I was 13.
However, my current feeling is that one w and one y per name is probably enough - there are exceptions sadly this isn’t one of them.
I like [name]Spencer[/name] better. I also like the nn [name]Spence[/name].
That’s a tough choice. I like both but if I had to choose, I would pick [name]Spencer[/name].
I like [name]Sawyer[/name] [name]Hayes[/name] better as a combo, and I think I like [name]Kellen[/name] and [name]Sawyer[/name] better as twins, but [name]Spencer[/name] is on my list, so I have to say I love it. I love the way [name]Sawyer[/name] looks, but I like the sound of [name]Spencer[/name] so much more. Either is lovely, though! Now that I’ve been saying this, I am really growing to like [name]Spencer[/name] [name]Hayes[/name], too. But I think [name]Kellen[/name] and [name]Sawyer[/name] are more distinctive, so I think I still vote for that.
Good luck!
Definitely [name]Spencer[/name]. I think it’s an up and comer, but not as trendy as [name]Sawyer[/name]. Goes nicely with [name]Kellan[/name] and mn [name]Hayes[/name]. [name]Spencer[/name] [name]Hayes[/name] is just lovely’
[name]Spencer[/name] sounds so childish to me and I cannot imagine it aging well. [name]Sawyer[/name] sounds rugged and handsome, but also passable on a baby and child. [name]Sawyer[/name] [name]Hayes[/name] looks really nice together. I think with twin brother’s name being so masculine, this one would sound good with a more masculine name too.
I prefer [name]Spencer[/name], particularly paired with [name]Hayes[/name]. The repeating y’s trip me up with [name]Sawyer[/name] [name]Hayes[/name]. [name]Sawyer[/name] also seems to be going to the girls where I live, don’t know whether that’s a concern to you or not.
As a combo I think [name]Spencer[/name] [name]Hayes[/name] has a better overall sound. However, I’ve never seen the appeal of [name]Spencer[/name] so I would pick [name]Sawyer[/name]. [name]Sawyer[/name] [name]Hayes[/name] sounds nice!
I have a cousin named [name]Spencer[/name], so I am partial to it! 
I do really like [name]Sawyer[/name] too though. I would pick [name]Spencer[/name] because it is less trendy that [name]Sawyer[/name]!
I’d go with [name]Sawyer[/name]. Two y’s in a name don’t bother me, and how ofter will you call him by both names? [name]Spencer[/name] just seems a bit uptight to me.
[name]Spencer[/name] [name]Hayes[/name]!
I really like [name]Sawyer[/name] [name]Hayes[/name]!
I understand why people say the "y"s run together, but as long as you don’t always call him by both names, its fine!
[name]Sawyer[/name] and [name]Kellan[/name] make a great twin set!
good luck
[name]Spencer[/name] by a mile!
I agree with what @ashthedreamer said: I love the way [name]Sawyer[/name] looks, but I like the sound of [name]Spencer[/name] so much more.
I think that [name]Spencer[/name] sounds much better, especially with mn [name]Hayes[/name] and alongside brother [name]Kellan[/name]. =]
Another vote for [name]Spencer[/name] [name]Hayes[/name]. I like [name]Spencer[/name] better as a name than [name]Sawyer[/name] anyway, but I also think [name]Sawyer[/name] [name]Hayes[/name] has too many repeating sounds.
[name]Sawyer[/name] is nms but I think [name]Spencer[/name] [name]Hayes[/name] sounds great
