Re: [TomAiello] OSP2
The control response on both is just fine, exactly what you would expect from slow and docile 7-cell BASE canopies of older design. Easily as docile as my two OSPs were. However, they lack the topskin slats, which means they do not have the same deep brake performance and "easy" flare characteristics: you have to think more about the timing and nature of your flare. I found I became lazy under the OSP because you can safely flare from quite deep brakes.
There are trade-offs with the OSP. For example, it may be really hard to stall it compared to (some) non-slatted canopies, and it may provide great stability in turbulent conditions, but it also lacks glide and wind penetration. I think the OSP is a great canopy for certain conditions, applications and styles; I loved it. I moved on because I needed to sell rigs and the OSP has good resale value. Also, Atair would not build me a custom one.
I think it's worth pointing out that most older BASE canopy designs are perfectly airworthy; I had qualms about buying my FOX xs because of the age of the design, but ended up respecting and enjoying it. It's ideal for my limited jumping style of mid (300') to low (114') objects using assisted deployment methods and short delay handhelds. Also, I am past 50, only jump slider-off and have no desire to utilize a faster BASE canopy that requires better reactions than my ageing reflexes can provide.
When considering a new OSP-style canopy, it might be worth investigating Bad Seed's new Beast.
