I was looking at something else over there and just searched GRCS

Great vids!

The GRCS and the Hobbs Lowering Device add a whole new dimension to tree rigging. I bought my first Hobbs in 1989 and GRCS in 2003. Both great are great devices.

Here's an anecdote for you guys. The biggest complaint I have heard about the Hobbs is that it takes two guys to carry it into the back yard.

Well, field testing some of the early prototypes (remembering that there was NOTHING like this on the market at the time) the crew and I reported to Ed that it just worked GREAT, didn't break and did a good job; but it was AWFULLY heavy. So he proceeded to pick it up with one hand, gave us that "someone needs to get stronger look" and said "but it didn't break, right?" That's what he cared about. Nothing was heavy to Ed, he was the proverbial bull of the woods.

Great videos.

I have been wanting one of these toys since I learned of their existence.

A few questions for those with experience using them:

How does the "gerks" rope brake compare with using a large port-a-wrap, and how does lowering off of the capstan compare, in terms of speed, efficiency, control, ect., with using either the port-a-wrap or the GRCS brake.

For example, say you have a large backyard tree over a pool and tile patio where you have lots of chunky wood to lower, but the job is straightforward with plenty of room to work, and you do not anticipate needing to be able lift from your rigging points.

Will you:

A) Use the lighter and, I presume, easier to install port-a-wrap.

B) Use the gerks brake.

C) Lower off of the capstan, just in case there is an unanticipated need for it.

D) Leave it all in the truck, take the day off, and swim in your customers pool until they get home for work and ask you what the #*&%& you are doing.

E) Other.

A lot of lowering in a big removal is when a trunk mounted bollard really shines over the porta-a-wrap designs.

Too true.

There are times when a Porty is the tool for the job, but having the low friction option is much better.

If just doing simple rigging, with The Winch you can remove all slack, and tension the system with one hand.

One guy I work with can run a drift line in one hand and a but line in the other. pulling the tip in and letting the but out when working with light loads.

I still will use natural crotch and trunk friction from time to time, though I'm more likely to lace the rope in the tree then have the ground guy try to appraise the need for friction.

Not to steal the thread, I use a bollard all the time though it is heavy (I am sort of a bull so it doesn't bother me) I would rather it to a port a wrap any day. I am really saving up for a GCRS I think it would make me a much more efficient operation. JPS keeps telling me they are great and if a good old devil dog say something he means it.

If a bollard is a 9mm, then the GRCS is a match grade Colt 1911
