Grounding question

I purchased one of the $19 grounding blocks from Stein (http://www.steinair.com/storedetail.cfm?productid=310) and mounted it on the firewall near the battery, in the cockpit. I'm bringing the bulk of my grounds there (all the avionics, the EFIS's, AHRS, VPX-Pro, and all 10 of the VPX switches) to this ground. Its the screw kind of ground bar that uses the crimp on ring connectors.

I can either stack 2 or 3 ring connectors under each screw, or I can take the 10 switches, and perhaps some of the other low voltage wires and splice up to 3 onto one wire and take the single wire to ground. The latter method seems neater but potentially adds a failure point (the soldered splice).

Is one method preferable to the other?

Don, what you're proposing is essentially an avionics ground bus, which is what I'm doing. I've got one of B and C's 48 tab grounding strips (http://www.bandc.biz/groundblock2424-tabfirewallkit.aspx) mounted to an acrylic base (to insulate it from the air frame), and then I'll run 4 heavier gauge wires from the avionics ground bus to my firewall mounted ground bus, which is another B and C 24 tab ground bus.
