I've only ever used the following brushes so can only compare them to this brush : Bentley, mono vikan rect, superlite mark 1 and mark 2 (the ones without the indent on the stock) and the Ionics black double trim. I'm comparing it to the SL in the text below, because I think that is the best brush of them all.
Report on the Aquafactors 12" Double Trim brush.
Whether it's a Tucker or not (they still haven't contacted me about it which is kind of annoying) it's a decent brush. Definitely better then the SL I've got.
At stock it's a bit heavier then the SL brush being about 400g including headstock, jets and tubing. Compared to the 300g of the SL mark 2. I've probably been spoiled with the low weight of the SL, but you can really feel an extra 100g. Anyway, I drilled some holes in it and shaved off about 50g.
It splays very well, I never understood dual trim brushes where the inner trim simply didn't engage the glass without pressing down hard on the brush. It defeats the purpose of having a double trim and greatly reduces scrubbing power. This brush does splay very well and fully enables the inner trim to contact the glass, greatly increasing scrubbing power. In lack of another word, it really melts on the glass, if that makes any sense. Now that it's slightly less heavy it needs a bit more pressure on ground floor windows, but it's still fine.
The bristles are fantastic, being clear you can see any dirt in the brush. The brush also retains little water so doesn't get weighed down by it.
The brush stays very clean and is ideal for rinsing with the brush on.
The brush glides very very easily over glass and frames. Just like the SL, on traditional leaded lights it does skip a bit, but it's less. Around 25% less or so I would say.
On recessed Georgian panes there is more resistance I would say then the SL, but on normal Georgian panes there is less resistance.
The brush is much more effective on extreme angles, and can scrub much better on said angles.
Also with spider nests the brush is very effective and just flicks it out, probably due to it having much more bristles.
The original holes are not a great placement for pencil jets. The pencil jets need to be further to the sides, because it makes it much more difficult to rinse corners, often having to lift the brush to one side, or have the bristles hang over the frame. I've now put it about 1.6cm from the sides, which is much more like the SL brush.
