I just recently got the DCF WP IIs in 8X42. I am a devoted turkey, deer, and waterfowl hunter. The major reason I chose the WP IIs was because of the tougher (though somewhat heavier) frame and better optics (at least that is what I read on this forum). I will be using these binoculars in a variety of conditions and wanted the toughest bino I could afford.
I researched the purchase for nearly a week and decided that this was the best bino I could afford. I don't know much about the HR IIs other than what I read from the Pentax website. The major difference to me was that the WP IIs have better glass and are made made on an aluminum frame. The HR line has a "polycarbonate fiber reinforced" body (plastic). They both contain phase coatings, nitrogen purged and are JIS class 6 for water resistance. Both carry a lifetime warrenty.
I have now used the binos for a couple of weeks deer hunting in West Tennessee. I absolutely love them. They are very bright in low light conditions, very clear and sharp (at least I think so but I am no optics expert). They really have exceeded my expectations, which were very high to begin with.
I am very certain that I made a great choice in picking the WP IIs and I couldn't be happier except for one small thing >>>>>>>>>>> the click stop feature on the right dioptor doesn't appear to work (doesn't click and has no detents - the wheel just turns like all the others I've used). I called Pentax and to verify the fact that the bino has this feature, which keeps the dioptor adjustment from changing once you set it for your eyes. Pentax said that it should have this feature and that I should request a replacement from the retailer (Amazon.com). I called Amazon and they sent me another one promptly, but guess what >>>>>>>>> no click stop on the dioptor wheel. I call Pentax again (office is in Denver and they were snowed out for two days) and told them the story. The customer service guy was very nice and said that he would research it in the sports optics department and call me back. Either this is a misspelling in their advertising or they have a bad lot of the WP IIs out there without a feature that they are supposed to have. This was an attractive feature that I really wanted, so it will be interesting to see how this is resolved. Stay tuned.
