I have a set of bogen legs and need a good fluid head for them. I'm tossing the pistol grip cause it is junk! It mostly will be used for my sts 80 swaro spotter. I have a Jim White pan head for my 15x56 on slick legs and love it, but its not enough for the big spotter. Any advice would be great. thx. If you could add price range that would be good too.
