Ok, just my opinion though.
I love my 440s. I have ridden Speedies/TBAs with both and chose the 440s because they assist in gripping the road nicely and have much more adjustability to them. They screw up/down linearly so it is pretty much an infinite adjustment, not just 4 clicks and you choose. Nice feature for us folks that keep getting larger.
But, like I said, just my opinion, and we all know about opinions, eh?
