I don't think applying in R1 vs R2 makes much of a difference. Tuck's ED deadline is right around the UE's R1 deadlines. While Tucks R1 is more like a R1.5. I think that you are better spent worrying about the quality of your application than which deadline you make. If you put together a weak application it wont make a difference but if another month would allow you to make it much stronger then you are way better off doing R1 vs ED.
That said there is plenty of time right now to get the app together and make it solid. I have thought about it and unless I can tour one of the first few weeks of September I will go R1 instead of ED just to allow myself to visit the school.
Personally I think most people who have never been to Hanover before owe it to themselves to visit before applying to Tuck if at all possible. It is a SMALL TOWN, there is not much to do, winters can get downright nasty at times, and it is a small school. Its a beautiful area but you better like hiking and skiing cause the choices for social activities are very limitted. I personally love the area and would choose it over NYC anyday but it has a lot of limitations due to size and location.
