I've found the Travel Tap to be the easiest to operate filter system I've used, although squeezing water through the filter does take a little bit of time and effort. Having read many glowing reports of its performance, I've felt no need to boil water after using it, and have suffered no ill effects even after taking water from less than ideal sources, like peaty pools.
Having said all that, I don't usually bother with it at all when I'm going to be where there is free flowing water above the fell wall.
I'd check on the pegs currently supplied with the Laser Comp before making any decision.The ones supplied with mine were too small and easily lost for use in anything but ideal conditions (about one week a year in the UK, on the right terrain) so I replaced them with a selection of others, to cover a range of conditions. Other than that it's an excellent tent that's stood up to a lot of use in some pretty harsh conditions.
I've not used any Berg stuff or even seen it in the UK, but the fact it's not widely available here doesn't mean much. I've bought a few bits of Zajo gear from the same website and although there's very little reference to it on English language sites it's proved excellent.
Not that bad a price for Dead Bird boots, I suppose, and they do look pretty cool. Still, a water permeable outer with what amounts to a waterproof sock inside isn't a totally novel idea, and nor is the rounded heel.
