On the leg front, i'm still undecided. But will definitely look into the feisol!
took a quick look at that head on B&H - seems as though it does have a friction preset lock. But 1.9lbs!!! I thought about getting one of the manfrotto RC4 plate heads, as I was already using 2 rc4 plates (along with) the knockoff plate I had on the amvona ballhead. Also looked at the higher end cullmann and giottos heads (looked at some velbon and even the gitzo heads at a local shop in this range) - somewhere in the neighborhood of $120 upto $150.
That step up into the $200+ range of heads, in retrospect, was really worth the money. Obviously the weight ratings any company gives are somewhat of a guide, usually a static weight in a balanced position, that sort of thing. The manfrotto head you were talking about I am sure is nice, but it is a downright beast! It is 3 times the weight of the photo clam head I ended up with.
The amvona head I have weighs just over 1.5lbs (it is actually a knockoff of the 488rc4 model, probably essentially the same as what you have, minus the quality, haha), and although it is kind of a grease monkey (literally, kind of gunky stuff on the ball, typical for the knockoffs), it locked down great, I never had a fear it would come loose at all.
I now have a smaller head, that weighs only 40% of the amvona head, and I feel even more confident in its' weight bearing ability - it locks down like a rock with the k20/grip/50-135 - and it only weighs 10 ounces!
What I was attempting to say is (and I am presuming this may be one of your thoughts at the moment) - I initially thought to myself hey, I've already got a couple plates, so I'll move up to a legit ballhead from the maker of the plates I already have (or, in your case, a bigger model with better features). What I realized was that I shouldn't let a couple of $15 plates decide a $200+ head purchase.
Whatever you end up with, you have to keep the thread upto speed!
