If it were me, I'd pin it.
My three reasons;
1) The manual says to;
2) Those aluminum clamps seem fragile, and I'm always afraid of over tightening;
3) I saw an interesting failure of a G-something rotor a couple of years ago
that I'd attribute to an unpinned mast. Continual minuscule back-and-forth
mast slippage caused the steel mast to cut a round hole into the top of the
aluminum housing of the rotor. Sawed right through into the guts, causing a
catastrophe. May not happen if you have a TB holding all the weight, but.....

Subject: Re: [TowerTalk] Pinning my mast in rotator clamp
I have never drilled through the mast & bolted. Have had to climb the
towers a couple of times in the last 20 years to readjust when we had high
winds, and the mast slipped a little in the clamps. I would rather have to
do this once in awhile than have something break in the rotator.
