I have ran them all season on my Snapper Pro 48 (NON - ICD) and the difference is night and day. Two weeks ago I put some standard high lifts on. I first noticed they were allot quieter then the G6. They left a good clean cut, but the clippings were horrible. I immediately put a set of G6's on and been happy ever since.
I removed all other types from the rotation. They sure work great for me.
