FLM or GH bulkheads?

[mothman]

Im upgrading the bulkhead but not sure which one to get. Th FLM looks good but lack of easy access. The GH has the easy access but doesnt look like it is cnc machined. and from what I have read, the quality of the machining (the tolerance is a bit off). The flux diff doesn't really fit in it.

So between these two, which one would get? My main concern is the durability not so on the easy access..Anyone managed to break either of these bulkheads?
