> I'd really like a big pad but even with an Octavia estate the size in the back puts me off.
My friend has an Octavia estate and it is quite easy with the seats down to get his Saturn Pad + my Organic Big Pad & 2 highball pads as well. I can get that all in my 3 door fiesta but you can't see anything and it is a mega squash especially as the Saturn doesn't fit across the back seats as easily due to it being a bit bigger in size and not being a rectangle but a squash tube shape.
Because of this and being someone who uses my pads almost daily in winter being able to keep the big pad + a highball on the back seats almost all the time and still see out of the back, whilst still having the boot free and not compromise the foam as much by having it always folded was a big plus. Having to store the Saturn open to stop the foam creasing would be a right pain for me although the lack of fold is usually a advantage at the crag. They are both similar in impact absorption although I have noticed as the review did that the Organic starts harder, almost too hard but ours both bought about the same time seem to be holding up well so far although mine sees a little more use than my friends.
I don't know about other users but I find on the Organic Big pad the back system being held in place by velcro is a particularly weak spot. After a short time the velcro on mine has failed and the pad now slides from side to side if I have a heavily load stuffed inside it. A friend sorted this out by getting the back system stitched in place, something I intend to do to but wouldn't have expected to do for the price! Although I have regularly taken it out with a trad load inside which hasn't helped, something that the review says isn't practical although I have managed ok, although i don't think it does the foam any good and puts a fair bit of strain on the buckles although these are holding up perfectly which shows its build quality. The main disadvantage is with a trad rack inside the pad it bends the foam so it isn't very comfortable to wear.
I tried out the Alpkit very briefly at a crag once and it was a joy to land on (especially compared to their early offerings in the early 2000s) the owner was impressed with it too however mentioned that the outer material seemed to be oversized compared to the foam so when carrying it the foam of the pad would swing around inside causing a similar problem to my organic.
I borrowed a Petzl Cirro for a several months once and whilst it was a joy to land on the weight, similar car faff to the Moon Saturn and time consuming zip closer system meant carrying it a short distance between problems was so much of a pain it put me off buy one when I had to give it back. I managed to overcome this problem somewhat by taking two karabiners to the crag to clip the opsite ends of the pad together but a bit of better design and this wouldn't be a problem. The zip closure system felt like it was about to break too which was worrying as it was on loan so for someone who is heavy on their kit this was also a worry. Carrying stuff inside I liked that the stuff couldn't fall out the bottom but again having anything more than basic bouldering kit squeezed inside was a pain and put alot of strain on the world's biggest and baddest zip. The velcro hip system was also terrible and keep coming undone which for a heavy pad was a right pain, what was wrong with a buckle (don't remind me of a trip to Sypeland with this pad a trad rack and a highball I almost died). Having said that if I had a choice of which pad to take a big fall onto this would be a favourite.
