I'm considering buying either a Arcatech GP or GV2 ballhead.
The difference between the two other than the $60 cost is, the GP offers a built in leveling base for doing stitched panoramics.
There is a bubble level on my tripod and also on the head clamp so, would I need the leveling base feature of the GP?
If my tripod is level and the tripod head is level, would this not accomplish the same thing as the leveling base?
I generally don't do many stitched panoramics but, I have from time to time so, i'm just wondering if the extra $60 feature is really needed.
On the other hand, for $60 more, it appears to be a good deal when it would cost almost double that amount to buy the leveling base seperately if I went with the GV2 model.
