I use a Sigma with Sigma 370 main. I like it but it is a little bit wide at the shoulder for me. So that I considered the Sigma Micro. Is there any other difference than size between standard and Micro Sigma? Anyway I have no problem to pack the Sigma 370 main into the container so I thought putting the HOP330 into the Micro would be the same. Is it not right? Robert

Other's opinion about Sigma Micro? I am just hesitating between a normal Sigma with Icarus 365 main and a Sigma Micro with HOP 330 main. Robert

Try to balance the turn with resetting the left or right steering line at the toggle. Robert

Line trim is ok? Primary/secondary brake lines? Robert

Faster how? Not altitude loss. Think about this: you have a low speed cutaway with a skyhook from a fully inflated main (lets say it's just not controllable), the skyhook does it's job and your reserve opens in 150-200'. Now, on your next jump, you have a bag lock, you cutaway, and the skyhook does it's job. Do you think your reserve is going to be open in the same 150-200' that it was in the low speed situation? I hope not! The same concept applies to any scenario where the rate of decent may be accelerated. Yes, there may be other variables such as getting deployed to the side from a spin, but which way is the reserve going to be facing when it pushes the slider down? Is it going to be facing the sky, so that it will level off quickly, or will it be facing the ground, in which case it will dive (and loose more altitude)? In time you may get a faster deployment from a spinning malfunction with skyhook, but the altitude loss is probably the same. Take account that the spinning canopy have a considerable vertical descent as well so what you win from the spinning that you loss with the vertical speed. Robert

Paratec bulletin from 09/08/2004: 'During a routine control (straightening the cable after an RSL activation) came to attention, that the swaging of a reserve ripcord pin was insufficient, causing the ripcord cable to disconnect from the pin with very little force. The same happened with 4 other ripcords (3x Next Student, 1x Next Tandem)' PdF bulletin from 09/15/2004: 'A user reported the breaking of one of the coated cables of a MMS metal cutaway handle for main canopy' UPT (RWS) bulletin from 01/30/2007: 'Ripcord damage found in field on January 18, 2007. Rig was an older Vector II.' Robert

They are talking about pro packing in the new sigma manual. Robert

Bill, Will you offer them for Sigma tandems as well? Robert

If my calculation is correct the van should go down at about 230 mph in a 20% grade to reach 45 mph vertical speed. Congratulate to the driver! Robert

I have a Jack The Ripper knife as well but some others prefer metal knifes for tandem. Nowdays a carbon fiber version appeared in the market. What do you think? Any experience? Robert
