I would avoid the RRS BH-55 for two reasons: (1) my copy had a catastrophic failure when I had my 500mm F4 mounted on it. The larger knob (the lock down knob) simply fell out of the space ("hole") of the ballhead. When I contacted RRS about this, they told me it was a known problem...the glue (or the application thereof) that keeps that part attached to the main part of the ballhead was misapplied, not applied sufficiently or for whatever reasons, had decayed and become undone. My ballhead looked brand new...and as I said above, this is a problem RRS knows about...
(2) I also avoid RRS products whenever possible because they were (and are) active in California politics in the attempt to defeat proposition 8 - the anti-gay marriage bill. Several of our (Deborah Allen and myself) friends are gay...and in the grand scheme of things, we believe everyone should be entitled to equal treatment under the law. What religions decree in church is a different matter...but if someone is gay, he/she should be allowed to be wed (in the legal sense), and receive the same protection/rights/benefits that every heterosexual person receives....
The Arca-Swiss head is fine for long lenses - that is what I use now when using a ballhead. However, if you are going to use a long lens, I highly recommend this $100 Chinese Gimbal head...I have it, use it and it is 100% fine with long lenses including the 800mm F5.6:
