Re: g2/g1 combo
Many drummers use the G2 /G1 combo and achieve good results. What you said about the difference between the 12" and 16 " toms may be true, although many drummers have the same sizes. When I played those sizes, I did not like it, so I went 13" and 16". My current set has 12" and 14". Good luck. Peace and goodwill.
