I have to agree with this, the OP two choices are made way different.

This is a pretty bad design compared to this. The first one has a pretty bad inlet path compared to the second one. The curved funnel effect is a PROVEN design. I have heard the smaller filter size has also been a problem for some people.

I had an older Big Sucker crack at the breather tabs that bolt to the heads and a lot of people have had the same happen too. I have heard they fixed the problem but I have moved on to this that I blocked off the breather ports on the adapter and cut the mounting tabs off the back plate and used breather bolts and a Super E manifold with a press on flange adapter for the carb and used this cover for more knee clearance. Its not the most expensive but its designed incredibly well and isnt too flashy.

I personally like working and experimenting on the bike as a large part of the hobby.
