Rearend choice

[hotrod69camaro]

I will be having a Q-link and mini tubs done to my 69 camaro. I have read here, some of you guys talking about the extra effort it takes to turn a 9 inch. This will be the first time I have dove this deep into a rearend. Is this extra drag over what it takes to turn a 12 bolt a big deal or what. I searched as many posts as I could and read about the better pinion placement of the 9 inch. I'm fully aware of the easier gear change. Just thought I'd ask guys with more knowledge on the topic than me. Thanks guys.
