I have to say I tried to buy a Berghaus Roc/Cyclops/Crusader recently (was the bergen I had years ago before they issued the new one), but found the whole thing so frustrating I ended up bying an issue one cheaply. Haven't used it yet, but it looks almost the same as my old Berghaus Bergen, seems excellent.
The PLCE issue side pouches will fit, the lid isn't as large as the issue infantry pattern meaning stowing your daysack will be harder. Adjustable back is said to be the business, Dutch guys I met last month are chuffed to bits with it, new modular vest has been well received too. The saracen is already reaching Dutch army disposals. UK price from us when we get them is likely to be around Â£90.00 based on prices quoted to us. Sounds high for a used pack but these are around Â£200 new. OG and DPM coming through, anyone interested PM me.
I've not tried the Saracen, but I've been using a Salient for years now, and cant fault it. The only thing wrong with it after about 12-13 years use, is that the waterproofing has de-laminated from the inside. Lowe Alpine gear is really nice, if you can live without the side pockets, I'd suggest that the Salient is a better hillwalking pack as the slim design keeps your centre of gravity in close and offers better stability.
