Are you planning on cast/strip? or primarily swing?
For both, I've almost completely settled on the Orvis Bank Shot sink tip (I do WAY more cast/strip than I do swinging streamers for trout). With weighted flies it's really good for one back cast, fire away, and you're fishing. If you're needing to bomb casts way out there, I've found that it's just not as effective as a closer in game (out to 50') because it's easier to lose touch with your fly. If I need to get a little deeper, I have an Airflo Streamer Max Short that I'll sometimes use (this is what I always use for bull trout with pike sized unweighted flies). But the Bank Shot sink tip is way more versatile for most trouty sized streamers.
I can't speak for your rod, but on my glass 7 and 8wts, I go with that short of a head in the ~250gr range and bump up to 320gr on my Steffen 9wt and a 350gr on my Bandit 10wt for bulls. All of those can cast all of those lines just fine (well, except perhaps the 350gr).
For leaders, no longer than 5' of straight 12lb fluoro. 20lb (sometimes 25lb) fluoro for bulls.
