one club for all chips or various clubs?

This is an interesting one.....all the instruction I read says to get the ball rolling as quickly as possible on the green, so if you can use an 8i/7i, then do so. However, pretty much 99% of the low golfers I play with chip with a 56 or higher degree wedge.

Incidentally, I use a 7i as I am pants with a wedge.
