All good advice in this thread. I'm in the petzl rocpec camp. I used the pika early on and hated it. Also used the hurricane and didn't love it. Also used high speed steel bits and could never figure out the "twice" as fast thing. I found the bits to bind way more and slow me down. Finding a hammer that fits you is also important. I've tried the original A5, the new D5, the Mcdevitt, and a petzl one but I've always returned to my original BD wall hammer. I've got small hands and short arms and the smaller nature of the BD hammer fits me perfectly. I also don't swing super hard, I'm am more of a gentle driller and find my sds bits don't chip nearly as fast this way.
The one piece of advice that I never see mentioned in threads like this is to use Loctite or any of the available thread lockers.. Since the torque is so much lower on Stainless steel bolts the nut has a tendency to loosen up a lot. I can't tell you how many newish SS bolts I've come across that have loose nuts or the nut and hanger are completely gone. If there is a sling on the bolt the wind will the blow the sling back and forth and eventually loosen the nut right off. Seen this in Patagonia many times and around crags of the PNW.
And regarding the blow tube or pump. I don't actually believe it is necessary. When I started bolting I always used one but I forgot the tube enough times that I just used the bit to twist all of the dust out out. After awhile I just stopped bringing a tube. Not sure of my exact count but I know I have for sure placed over 300 bolts by hand and have never once gotten a spinner. Then I've had partners using the exact setup as me and they used a blow tube and they got spinners. I think it has more to do with drilling technique and precision than dust in the whole. The only asterisk to this is if you are drilling on a horizontal surface and the dust doesn't naturally want to work it's way out. That would be a good time for a blow tube.
