To change a mini provari to use the 650 batteries, you will need a tatroe ring and the extension cap, correct? If I am extending the satin silver mini, shouldn't I buy a polished extension cap to match better with the tatroe ring that attaches to the base? Would the flat base be able to be used during this arrangement? I'm a little confused....I have 2 complete tatroe stands-silver and brass- and extension caps for the red, silver, and black. What I want to do is extend the black or silver to 650 mode with matching pieces, help? Last piece of the puzzle, I saw a twins thing on amtistique for the mini, I think to do the same thing and would be the exact same color, type! If anyone has this on your units, please share pics so I can be sure that if I need to order more items to make my mini a 650 with compatible pieces that match!! Please advise!
