I think that if you have an opinion, then it's OK to state your opinion-but if you have no firsthand experience to convey, then you do nobody any favors by overstating your opinion.

Perhaps it's because I have a low-mileage engine and it doesn't get very cold here, but the upgrade on my '79 really didn't make much difference. I do get faster starts with the pencil plugs, but I never had starting problems to begin with. I went with the 80035's because they were only a couple of bucks more than straight replacements. If the loop plugs are in good shape, and you have clean pre-chambers, then they will certainly get the car going. They just take a minute longer.
I think sharing information is what the Forums are about; even if it is saying this is what others have said.
I the case of cooljjay He gave His opinion and said see for yourself.

In installed Monark Glow Plugs in My Car and one died about 1.5 Years later. That is in Southern California weather, Glow Plug Holes Reamed and low mileage driving on Injectors rebuilt 2 years before.

It was a sneaky one. It ohmed out OK but as you see in the pic it gets hottest in the middle of the Element.
Also after I took that pic and it cooled off I Ohmed it again and it failed and when I tested it on the Battery again it died!
