Whats the best main vent model?

Best?

That's subjective. The Gorton #2 is very popular for is capacious venting. But really, a little bit of understanding trumps a lot of information, here. Check out this reference:

$10 well spent, and it all goes to charity. Not only does this pamphlet include tables detailing the capacity of all the vents you're likely to come across- both main and radiator- it discusses HOW to choose the ones that are best in your circumstances. I see you have a few other posts asking similar vent questions, so I bet this would be a good reference to have. It's a good idea to think of your venting systemically, and this pamphlet explains this concept clearly.

Good luck,

Patrick
