Woah.. You guys type way faster than me.
If you're not doing a restoration to bone stock, I'd say go with those carbs since you've already got them. They're a little bit trickier to dial in, but works great when done right (Or so I'm told - still struggling with a clogged pilot line on mine).
But then again, you've already got 3 boots for the round tops, and if those boots are good, and you could exchange these carbs for a set of roundtops for free, then you'd only need to get 1 more boot. Less hazzle maybe? I don't know..
