Your testimonial validates the Subgravity website (though they could stand to post a few more pics from various angles). How small does the Paragon pack? Does it require disassembly to fit in a carry-on? Do you use dumpable weights in addition to trim? Did you order direct or go through a LDS?
Disclaimer:
1. I personally do not dive a Sub-Gravity backplate but my wife and oldest daughter each have a Sub-Gravity short stainless steel plate.
2. We all started with non-adjustable/Hogarthian style harness. I have rigged my harness to be adjustable similar to the OMS Smartstream adjustable harness.
I can attest to the quality and customer service of both HOG and Sub-Gravity. My youngest daughter has a HOG aluminum plate with their 23lb wing. My oldest, as stated above, has a SG stainless steel plate (short) with a HOG 32lb wing. Both companies make/market high quality gear, are easy to contact by email and phone, and offer excellent customer service. I would not hesitate to buy gear from either company in the future as our needs arise.
A few years ago I was brainstorming ideas on how to make my shoulder straps adjustable. I came across the Sub-Gravity adjustable harness (Paragon) and really like the buckles they use. I was living in Belgium at the time and could not easily source them at first. By the time I was able to find a reasonable source for them I had already arrived at an alternative solution that was an amalgamation of ideas that came together looking at products at the
Agir.se website (specifically their
battery carrier strap, and their
Harpa loop). It turns out that what I put together is very similar in concept but a bit different in execution to the OMS Smartstream harness, that I did not know existed at the time.
Although I am happy with what I have (Dive Rite stainless plate and 35lb Voyager XT wing), if I was able to go back in time with my current knowledge, to when I first purchased my backplate and harness, I would purchase the
Subgravity stainless plate and adjustable Harness which is essentially the same as their Paragon package without the wing. I have nothing against Sub-Gravity's wings but I like the quality of my Voyager XT wing and Dive Rite offers a lifetime guarantee on it, but if you are looking for a "single source" package and are already considering the Paragon then I would recommend it.
As for packability...we are talking about a stiff metal plate that is approximately 16-inches long by approximately 10-inches wide, it ain't gonna get any smaller for packing purposes unless you have a shrink ray. The wing will detach easily enough to fold/roll for packing (I recommend removing the corrugated hose assembly from the wing when doing this). There are discussions on ScubaBoard and some videos on youtube for
converting/attaching a backpack to the plate in order for it to be conveniently carried/worn and pass as carry-on luggage.
As for weighting/balast...my setup allows for both ditchable and non-ditchable weight depending on the exposure suit I am using (wetsuit, semi-dry, dry). You will need to dive whatever you purchase a few times to get things dialed in right for you.
As for purchasing our Sub-Gravity plates...we purchased through
Dive Right in Scuba (DRIS). They don't list the Sub-Gravity plates on their website but they carry them in their brick and mortar shop and were happy to ship to us after a quick discussion via their website's chat feature followed by a phone call to give them my credit card number. I could have purchased directly from Sub-Gravity but the cost with shipping would have been the same. DRIS is another diving resource that provides great customer service.
As for purchasing our HOG gear...we purchased our HOG gear through
Jim Lapenta (who posted earlier in this discussion thread). He is an authorized dealer/representative with a wealth of knowledge and he provided us with both information and confidence to outfit our daughter with her first BP/W a handful of years ago.
All in all, you can't go wrong with either system you are looking at.
Hope that helps at least a little bit.
