I'm another Kistler fan! 5 of them and slowly converting all the others. They are very light and sensitive. I personally like not having the cork foregrip. It's more comfortable to place my finger directly on the blank.

I do think that the Helium series are rated a little heavier than they are. Meaning, if you normally use a 7' MH for whatever, check into a 7' H with the Helium. But that's just my opinion.
