I use Okuma Integrity reels for the Striper fishing I do, and they perform just fine. However, I'm primarily fishing in tidal rivers & creeks some backwaters & don't do much in the way of surf fishing so they don't get dunked.
I use a floating line most since I'm primarily fishing shallower waters but have sinking lines in various sink rates, mostly to deal with variations in tidal current strengths. Again, not a surf fishing situation like might be found along the coast.
Clouser's are great as suggested, just be very careful about hitting your rod with them if you're not used to casting them. Open up your loops! Clouser's have accounted for a lot of broken rods!
There are many good Striper flies. From the reading I've done about NE Striper fishing on other forums, those guys are matching the primary forage much of the time. Find out what the predominant forage is at the time of year & have some patterns to match. However, much of the time profile & size is more important than colors. Just keep in mind that there may be various prey species available & might be what they want in a specific area, so it's not a bad idea to have a variety of sizes, profiles & patterns to cover your bases.
Here, I use a variety of basic patterns ranging from about 3" to 8" in length. Lefty's Deceivers, Clouser's, Clouser Half & Half's, Seaducers, and Rabbit Strip Eel patterns primarily, plus some others. Stripers are not usually particular, although they will sometimes key on certain prey species & sizes. I like basic baitfish colors such as olive & white, gray & white, with some attractor colors such as chartreuse & white thrown in. I also always have some dark patterns on hand, such as all black or black & purple. These are usually considered night time colors, but they may make a difference on overcast days or in other low light conditions.
I'm sure Rip Tide will also be along to give you his advice since he's a NE fly angler!
