I hate it when someone chimes in when they haven't used the items. So I am officially pissing myself off.

Here Goes:
I haven't used either, but I have used several Vintage Gillettes.

After closeness of the shave I have two additional preferences. Balance and a little more weight to a DE.

I have 2 adjustable razors (Fat Boy and a SuperSpeed) along with 6 other TTOs. I like the heft of the Fat Boy and the balance of an older Non- adjustable Superspeed Flair Tip over the SupereSpeed Adjustable. The SuperSpeed Adjustable shaves fine but it feels off balance when I am shaving.

If the balance of the parker is good with a little additional weight in my mind I would try it first.

If anyone owns the Parker and can speak to the weight and balance I would appreciate it!
