I have used the 3047 head for 4X5 and 8X10. It is rated for 16.5 lbs, as I recall, and my Deardorf comes in at about 13 lbs. I am, however, moving into a Majestic geared head for the 12X20 since it comes in at 23 lbs plus lens and holder. I am not familiar with the particular Bogen Tripod that you have so I can't comment on that. I guess that the only true way to determine is to try it. If it is not solid enough for your usage then it will quickly become apparent. One can not be "too" solid but can certainly be "too" unstable.
