Pulling over a stem/mini MA system in action

Couple of pictures of my Mini MA system in action this week pulling over a large diameter stem from a big poplar fell

3:1 below on the ISC and the mini MA on top on the pinto

Not abundantly clear from the pictures but basically I set up a standard 3:1 MA on the rigging line using a large lowering block anchored to the cherry tree, this then went back to a Pinto rig attached to the rigging line via a 14mm sirius split tail blake hitched to the line. I then attached My mini MA to the pulling end of this line. This basically meant I had a 3:1 advantage pulling on a 3:1 system, now I'm not sure what this means mathematically speaking (maybe 7:1?) but all I do know is the two guys pulling the stem over had no trouble at all.

I'm sure this is nothing new to a lot of you and setting up mechanical advantage to pull a stem over is fairly standard practice. However I know in the past setting up anything more than a 3:1 just with a rigging line and pulleys uses up a lot of rope very quickly, even with a 60m rope you quite quickly run out of rope unless your anchor is very close to the tree your pulling over.

So by being able to use the Mini MA system on the end of the rigging line this issue was negated as well as considerably cuting down on the setup time. 

I have a video of the stem coming down I will upload at some point. 

New toys - Dmm Pinto and Pinto Rig

Couple of new toys I brought recently, I've had a normal DMM Pinto since they came out, but have wanted the rig version for a while now.

I've used the pinto for redirects, both of the climbing and lowering line, mini haul systems and occasionally speed lines. Having a few at my disposal will just give me a few more options.
I know you shouldn't use personal climbing equipment for lowering and vice versa, but I have done previously in the past. But now I can use the rig, exclusively for rigging and the normal pintos just for climbing.

As a quick redirect or for small scale lowering, the rig will live on a DMM steel oval with a short lyon sling, set up like this it takes up little room on a harness and can be carried on the off chance you may need it, rather than having to wait for the groundy to dig it out of a bag and send it up. I used to do this with the normal sized pinto, which was fine but not ideal for a 16mm lowering rope.

I was also toying with the idea of having a mini 2:1 haul system on 10mm line set up for pretensioning the lowing line and think that they would work well for that, especially as the beckets are rated. Just with 10m of rope or so in a mini stuff stack. Although this would obviously mean I could only then use them for rigging.

Something like this, but ideally I'd want to be able to quickly attach/detach it to the lowering line, anyone know of a 16mm mechanical ascender that would do the job?
