far out. thanks. I do like the styling of the mini better, that was one thing. and I think with the ability to run the same battery set up in the mini as the full size, with this twins telescopic extension, it might be a done deal. Will ProVari void their warrenty because of the after market extension and bigger battery I wonder? I broke down and sold one of my Nikon Nikkor DSL lenses to liberate the funds without the wife getting too upset, that way, when she wants one I can say back to her what she told me "It's just a battery". lol. my guess is that liberating those funds for a second one won't be so labor intensive. cheers all, thank you all for the input. couple more weeks, I am ordering. Nothing set in stone so keep those experiences and opinions coming. as always, thank you.
