[Amps] Direct-grounding SB-220 grids

I'm thinking about following several people's advice and direct-grounding the grids on my SB-220.  I'm told that this can result in a bit more gain and enhanced stability.  Merits of the procedure aside, if I do so, should I use copper strap of some sort, or will large diameter copper wire be sufficient?  Should I ground each grid pin directly to the adjacent chassis ground lug, or somehow connect them to each other?  It appears that each ground connection will only be about an inch long.
