Re: [obi] Which gear?
Well, many Q here...
I'll give you my opinion and also some info about the Troll DW here.
Obi, you are trying to find the most suitable gear for WS flying, right?
Regardless of my personal preference (Troll & WXtreme) I want to say that as long as you have any BASE-specific canopy and pin rig on your back, you're gonna be OK and on the safe side.
.......but, if you're really looking for more advanced stuff, here it is:
Rig:
Why WS Xtreme?!
WX rig was designed for WS BASE on the first place. It has a low profile, it has upper closing loop like the skydiving reserve containers (keeping the low profile of pack, no matter how bad the pack is), it also has dynamic corners and spandex pocket and additional small pocket for securing a bridle (in case of using the PC pouch (like with S3, V1 suits)). You can get WSX with a soft yoke (no 3-ring) and in that case it is really comfortable, low drag rig.
Other rigs:
All of them are OK as long they are one-pin or two-pin rigs.
Canopy:
All you need is the non-vented, small packing volume specific canopy.
If you need the canopy just for WS BASE, than the choice is easy. Take the canopy you trust in and that's it. If youre going to combine WS BASE and other low, sub, or high alt BASE jumps, it would be better to consider a canopy with secondary inlet (no need to explain why - it was said so much about that already). To make WS BASE or terminal tracking w vented canopy is 100% OK. Openings are sometimes a bit harder, which is better than dealing with snivelling anyway. An option to slow down the opening by using the small mesh slider is always there anyway.
The bad side of having the vents for WS BASE is bulk, but that is a minor issue.
The easiest way to avoid this bulk problem is to have two canopies ;o)
I can't say much about other canopies than Troll, since I have done only a few jumps on Fox and Mojo.
Troll:
The Troll is on the market for over 5 years now. During that period, Troll has been tested and tuned in order to assure good openings and nice glides and landings to their users.
The opinion placed by Tom a few years ago was based at the very first series of Troll canopies. This was solved by simply increasing the size of the cross ports.
For over the 4 years Troll (no MDV) had no problems w slider off openings.
There are some ''strange'' openings we can see on all of the canopies occasionally, both in BASE or skydiving and it will take many, many years to find all the reasons why something happens despite of all the knowledge we have.
Flight characteristic of Troll are great. Glide ratio is the best I have seen in BASE so far.
At the time the Troll was designed, the glide ratio and a good penetration into a head wind were the main focus.
As we all know, sometimes the forward speed (in a full flight mode - not during the openings) could be a bad thing to deal with if the LZ is small and require a steep approach. Exactly that was the reason for making the next step in ATAIR.
Troll DW is designed for tight areas as well, were the steep approach is required and at the same time the openings and the glide remains the same.
