Could not agree more. I have problems with blackouts on a a lot of the type 1 Naglers and the 16mm T2 Nagler. I find the 35mm Panoptic (which others have no issues with) absolutely horrendous.
One of the easiest eyepieces to use from a comfort viewpoint that I have used, outside my Pentax XW's. My 17mm Nagler T4 sees a lot of focuser time, as it hits the sweetspot in the 18" for a lot of DSO's. It does need a paracorr to give a good view across the entire FOV in a fast newtonian but works beautifully when combined with a paracorr. As does the 22mm Nagler T4.
Never had a problem with this one either.
Here's where it comes down to the individual user. This is my absolute favourite high power eyepiece for lunar/planetary in both my 18" (300X) and my 14" (230X) and I have never experienced a blackout or kidney bean with it, and I have owned it for 10 years 
I know you spent your very hard earned dollars on the 14mm Denkmeier based on my recommendation, a year or more ago. Me recommending the 14mm Denk was pretty funny in itself on the basis that I own a 12mm UO HD ortho, 12mm Nagler T4, a 13mm ETHOS, a 14mm Pentax XW and don't own a 14mm Denk  I also know that you initially had some reservations with the 14mm Denk. Am I correct in assuming that on the basis you still own and use the 14mm Denk, you are happy with it? While I don't own the 14mm Denk I rate it as optically the best eyepiece around this focal length outside the 12.5mm Docter and the 12mm Nikon NAV HW which are a serious amount of coin, and a major waste of $$$$ on my old burned out retinas.
Of equal importance to eye placement is the ability to keep your head/eye still while you observe. If you move your head around like "Noddy the Clown" you will have a lot of difficulty with a lot of eyepieces. The ability to "find" the exit pupil and then hold your head still is of critical importance.

Crickey John,
when I saw my post being chopped into quotes, I felt the sweat trickling off my otherwise chilly body.
And then I read on, Phew...!
Interesting point you made on the XW7
Regarding the Denkenemier 14mm...
When or when will I finally get around to putting my review of it on that thread- note to self- asap!
I get a few pm's asking about it from people who've seen the thread and want to buy one.
I love it!!!!!
The stars aren't as pin point as my XW or LVW- could it be the astigmatism it's picking up from my eyes that my other eyepieces don't?- I don't know. But that's okay- because everything else about it I absolutely love!!!! Nice black background- amazing contrast! It seems to have a slightly darker background than my XW10mm. It has a shallow cup and with that 20 degree eye relief, it means you can see the entire fov without having to get that close into the ep. Comfort wise, personally, I rate this even more comfy than the XW (in itself a very comfy ep). Seems to suffer the effects of dew a lot quicker than my XW's or LVW though- I wonder if this is because it has a very short eye cup
.
You steered me (yet again!) very well John in pointing me towards this ep.
Oh, I nearly forget- the advertised fov is supposed to be 65deg- I would say it leans more towards 68 deg.
After saying all that, I just realised this would make a good review for that thread, so I've copied & pasted from here to there.
