ive got the micro cylinder. it is certainly lighter than the stein bollard, but is it just me or do the smaller diameter bollards cause a lot more twist in the rope? I also cant seam to 'let them run' as well as with a bigger diameter bollard.

 

I also couldn't get on with the shizll. it looked super easy to adjust and slide down a stem for blocking down but in practice I found it a pain in the arse.

I don’t have any major issues with it, but there might be an aspect of rope selection there? My go to is 10mm rigging line and we work up from there. I do some pretty big rigging with 10mm too.
I think aluminium being softer you get a little more friction from it, so how you use it does need a bit of adjustment potentially.

As a caver I’d just like to set the record straight, we don’t use fig 8’s. 

 

I stand corrected, but you're still pretty odd fellows.

Caver Divers are even odder fellows. I did a little caving in the past, and enjoyed it. Physically forcing your body through tight little spaces with hundreds of feet of rock above you is one thing. Doing that under water, not even knowing when you'll break the surface again is off the scale. Upmost admiration and a little incomprehension.

There are tree friction devices that work like a Petzl STOP. They look fairly good for up-tree use.

Since owning a safe block the times the bollard has come out thr can are very few. 

 

But it's rare I'm working on fancy fancy lawns

[AHPP]

Crash gybe/jibe preventers look the best thing for up-tree adjustable friction. Not tried. They just look right.

Well that looks pretty effective. I like the bight feeding solution, but I feel the tooth at the top could be a bit more pronounced...

[AHPP]

Agree about the tooth. Could make it like a hammerhead (as in shark) at 90 degrees to the main plane of the device. More confident rope retention and would stand the slots and the rope off surfaces a bit.

Or just a taller tooth.

Yeah, a hammer or a round plate, that'd be ideal.

They recommend their own specific 11mm line for it, but it looks like you could squeeze another few mm into it, it looks pretty spacious.
